&lt;hr /&gt;
&lt;div&gt;&#039;&#039;&#039;Claimed by Carlos M. Silva (Spring 2022)&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Schrödinger Equation is a [//en.wikipedia.org/wiki/Linear_differential_equation linear] [//en.wikipedia.org/wiki/Partial_differential_equation partial differential equation] that governs the [[Wave-Particle Duality | wave function]] of a [//en.wikipedia.org/wiki/Quantum_mechanics quantum mechanical system]&amp;lt;ref name=&amp;quot;Griffts Quantum&amp;quot;&amp;gt;Griffiths, David J. (2004). Introduction to Quantum Mechanics (2nd ed.). Prentice Hall. ISBN 978-0-13-111892-8.&amp;lt;/ref&amp;gt;. Similar to [[Newton&#039;s Second Law: the Momentum Principle | Newton&#039;s Laws]], the Schrödinger Equation is an equation of motion, meaning that it&#039;s capable of describing the time-evolution of a position analog of a system.&lt;br /&gt;
&lt;br /&gt;
The free particle is the name given to the system consisting of a single particle subject to a null or constant potential everywhere in space. It&#039;s the simplest system to which the Schrödinger Equation has a solution with physical meaning.&lt;br /&gt;
&lt;br /&gt;
Although the free-particle solution does not have ample practical use in the field of Physics, the methods and conclusions that come from the solution of this system are of great use in a plethora of other quantum systems.&lt;br /&gt;
&lt;br /&gt;
==The General Schrödinger Equation==&lt;br /&gt;
&lt;br /&gt;
The general formulation of the Schrödinger Equation for a time-dependent system of non-relativistic particles in [//en.wikipedia.org/wiki/Bra–ket_notation Bra-Ket notation] is:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;i \hbar \frac{d}{d t}\vert\Psi(t)\rangle = \hat H\vert\Psi(t)\rangle&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Here &amp;lt;math&amp;gt;i = \sqrt{-1}&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Imaginary_unit imaginary unit]. &amp;lt;math&amp;gt;\hbar&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Planck_constant reduced Planck&#039;s constant]. &amp;lt;math&amp;gt;\vert\Psi(t)\rangle&amp;lt;/math&amp;gt; is the state vector of the quantum system at time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;, and &amp;lt;math&amp;gt;\hat H&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Hamiltonian_(quantum_mechanics) Hamiltonian operator]. For a single particle, the general Schrödinger Equation reduces to a single linear partial differential equation:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r},t)\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\Psi(\vec{r},t)&amp;lt;/math&amp;gt; becomes the wave function of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;. &amp;lt;math&amp;gt;V(\vec{r},t)&amp;lt;/math&amp;gt; is the scalar potential energy of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Time-independent Potential and Separation of Variables==&lt;br /&gt;
&lt;br /&gt;
The [[Potential Energy | potential energy]] of a system is often not an explicit function of time, that is &amp;lt;math&amp;gt;\frac{\partial V}{\partial t} = 0&amp;lt;/math&amp;gt;. Implying that, for such systems, the Schrödinger Equation of a single particle may be written as:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\frac{d}{d t}\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r})\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This, along with the [//en.wikipedia.org/wiki/Spectral_theorem spectral theorem] allows us to assume that the solution for this equation may be obtained through the separation of variables. That is, expressing the wave function as a product of a time-independent and a position-independent function:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) \equiv \psi(\vec{r})\phi(t) \rightarrow&lt;br /&gt;
i\hbar\frac{d}{d t}\psi(\vec{r})\phi(t) = - \frac{\hbar^2}{2m} \nabla ^2 \psi(\vec{r})\phi(t) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Expanding the derivatives through the [//en.wikipedia.org/wiki/Chain_rule chain rule] yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\psi(\vec{r})\frac{d}{d t}\phi(t) = - \frac{\hbar^2}{2m} \phi(t)\nabla ^2 \psi(\vec{r}) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dividing both sides of the equation by &amp;lt;math&amp;gt;\psi(\vec{r})\phi(t)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The left side of this equation is position-independent, and the right side of the equation is time-independent. Therefore, we have successfully [https://en.wikipedia.org/wiki/Separation_of_variables#Partial_differential_equations separated variables], allowing us to solve for &amp;lt;math&amp;gt;\phi(t)&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\psi(\vec{r})&amp;lt;/math&amp;gt; separatedely. Doing so yields:&lt;br /&gt;
&lt;br /&gt;

====Time-Independent Schrödinger Equation for 1 Particle====&lt;br /&gt;
&amp;lt;math&amp;gt;- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) + V(\vec{r})\psi(\vec{r})= E \psi(\vec{r})&amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours&amp;quot;&amp;gt;&lt;br /&gt;
====Space-Independent Schrödinger Equation for 1 Particle====&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{d}{d t}\phi(t)= -\frac{i}{\hbar}\left(E + V \right)\phi(t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A full derivation of this equations can be found below:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours mw-collapsible mw-collapsed&amp;quot;&amp;gt;&lt;br /&gt;
====Derivation of the Time-Independent and Space-Independent Schrödinger Equation====&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
Start from the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Take the derivative of both sides in respect to time:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\left(&lt;br /&gt;
\frac{\ddot{\phi}}{\phi}&lt;br /&gt;
-\frac{\dot{\phi}^2}{\phi^2}&lt;br /&gt;
\right) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
From now on, for the sake of simplicity, [//en.wikipedia.org/wiki/Notation_for_differentiation#Newton&#039;s_notation Newton&#039;s Notation] will be used to express derivatives. Simplifying the equation above yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\ddot{\phi}\phi = \dot{\phi}^2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Treat &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; as an independent variable and define &amp;lt;math&amp;gt;v(\phi) = \dot{\phi}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d}{dt}\left(\dot{\phi}\right)\phi = \left( \dot{\phi}\right)^2&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{d}{dt}\left(v(\phi)\right)\phi = v^2(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By the chain rule:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt}\frac{dv}{d\phi}\phi = v^2(\phi) \rightarrow&lt;br /&gt;
\frac{dv}{d\phi}\phi = v(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writting in differential form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{dv}{v}=\frac{d\phi}{\phi}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Integrate both sides yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{dv}{v}=\int\frac{d\phi}{\phi}&lt;br /&gt;
        \rightarrow \ln{v} = \ln{\phi} + C_1&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solve for &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt; and simplify arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
v(\phi)=C_1\phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substitute in the definition of &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt} = C_1 \phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rewrite in differential form and integrate:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int \frac{d\phi}{\phi} = \int C_1 dt&lt;br /&gt;
\rightarrow&lt;br /&gt;
\ln{\phi} = C_1 t + C_2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; and simplifying arbitrary constants yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\phi(t) = C_2 e^{C_1 t}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the Schrödinger Equation yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
C_1 = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Therefore:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\dot{\phi}}{\phi} = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
\rightarrow&lt;br /&gt;
- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) + V(\vec{r})\psi(\vec{r})= E \psi(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Which is the Time-Independent Schrödinger Equation.&lt;br /&gt;
&lt;br /&gt;
::&lt;br /&gt;
&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==The Free Particle==&lt;br /&gt;
&lt;br /&gt;
The free particle is a special case of the Schrödinger Equation where the potential is null (or constant) everywhere in space:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
V(\vec{r},t) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This potential is time and space independent, therefore we may use the equations found in the section above:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) = A\psi(\vec{r})e^{-i\frac{E}{\hbar}t}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) = E \psi(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The latter is a form of the [//en.wikipedia.org/wiki/Helmholtz_equation Helmholtz Equation]. There exists a general solution for an unbounded geometry in [//mathworld.wolfram.com/SphericalCoordinates.html Spherical Coordinates]:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\psi (r, \theta, \varphi)= \sum_{\ell=0}^\infty \sum_{n=-\ell}^\ell \left( a_{\ell n} j_\ell \left( \frac{\sqrt{2mE}}{\hbar} r \right) + b_{\ell n} y_\ell \left(\frac{\sqrt{2mE}}{\hbar}r\right) \right) Y^n_\ell(\theta,\varphi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Here &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\ell&amp;lt;/math&amp;gt; are quantum numbers. &amp;lt;math&amp;gt;a_{\ell n}&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;b_{\ell n}&amp;lt;/math&amp;gt; are amplitudes that define the wave packet. &amp;lt;math&amp;gt;j_\ell&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;y_\ell&amp;lt;/math&amp;gt; are the [//en.wikipedia.org/wiki/Bessel_function#Spherical_Bessel_functions spherical Bessel functions], and &amp;lt;math&amp;gt;Y^n_\ell(\theta,\varphi)&amp;lt;/math&amp;gt; are the [//en.wikipedia.org/wiki/Spherical_harmonics spherical harmonics].&lt;br /&gt;
&lt;br /&gt;
===General Solution in 1 Dimension===&lt;br /&gt;
&lt;br /&gt;
In one dimension our equation takes the form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
- \frac {\hbar^2}{2m} \frac{\partial^2\psi(x)}{\partial x^2} = E \psi(x)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Define &amp;lt;math&amp;gt;k^2 \equiv \frac{2mE}{\hbar^2}&amp;lt;/math&amp;gt; and rewrite:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\partial^2\psi(x)}{\partial x^2} = -k^2 \psi(x)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Assume &amp;lt;math&amp;gt;\psi&amp;lt;/math&amp;gt; as an independent variable, then define &amp;lt;math&amp;gt;v \equiv \frac{\partial\psi(x)}{\partial x}&amp;lt;/math&amp;gt;. Then:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\partial v}{\partial x} = -k^2 \psi \rightarrow&lt;br /&gt;
\frac{\partial v}{\partial \psi} \frac{\partial \psi}{\partial x}= -k^2 \psi&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{\partial v}{\partial \psi}v = - k^2\psi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rewrite in differential form and integrate:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int v \partial v = -k^2 \int \psi \partial \psi \rightarrow&lt;br /&gt;
\frac{v^2}{2}= -k^2\left(&lt;br /&gt;
\frac{\psi^2}{2} + C_1&lt;br /&gt;
\right)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;v&amp;lt;/math&amp;gt; and simplifying arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
v = \pm i k \sqrt{\psi^2 + C_1}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting the definition of &amp;lt;math&amp;gt;v&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\partial\psi(x)}{\partial x} = \pm i k \sqrt{\psi^2 + C_1}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writing in differential form and integrating:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{\partial\psi}{\sqrt{\psi^2 + C_1}} = \pm i k  \int \partial x&lt;br /&gt;
\rightarrow&lt;br /&gt;
\ln{\left(\psi + \sqrt{\psi^2+C_1}\right)}= \pm i k x + C_2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;\psi&amp;lt;/math&amp;gt; and simplifying arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\psi(x)= C_1 e^{ikx} + C_2 e^{-ikx}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Notice, however, that since &amp;lt;math&amp;gt;k&amp;lt;/math&amp;gt; is a function of the energy, this means a more general solution may be obtained by adding the contribution of many different energy levels:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\psi(x)= \sum_n A_n e^{i k_n x} + B_n e^{-ik_n x}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Furthermore it is possible to show that, if &amp;lt;math&amp;gt;\Psi(x,0)&amp;lt;/math&amp;gt; is known, then:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(x,t) = \sqrt{\frac{m}{2\pi\hbar i}\frac{1}{t}}\int_{-\infty}^{\infty}\psi\left(y\right)e^{-\frac{m}{2\hbar i}\frac{\left(x-y\right)^2}{t}}dy&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The Schrödinger Equation is a [//en.wikipedia.org/wiki/Linear_differential_equation linear] [//en.wikipedia.org/wiki/Partial_differential_equation partial differential equation] that governs the [[Wave-Particle Duality | wave function]] of a [//en.wikipedia.org/wiki/Quantum_mechanics quantum mechanical system]&amp;lt;ref name=&amp;quot;Griffts Quantum&amp;quot;&amp;gt;Griffiths, David J. (2004). Introduction to Quantum Mechanics (2nd ed.). Prentice Hall. ISBN 978-0-13-111892-8.&amp;lt;/ref&amp;gt;. Similar to [[Newton&#039;s Second Law: the Momentum Principle | Newton&#039;s Laws]], the Schrödinger Equation is an equation of motion, meaning that it&#039;s capable of describing the time-evolution of a position analog of a system.&lt;br /&gt;
&lt;br /&gt;
The free particle is the name given to the system consisting of a single particle subject to a null or constant potential everywhere in space. It&#039;s the simplest system to which the Schrödinger Equation has a solution with physical meaning.&lt;br /&gt;
&lt;br /&gt;
Although the free-particle solution does not have ample practical use in the field of Physics, the methods and conclusions that come from the solution of this system are of great use in a plethora of other quantum systems.&lt;br /&gt;
&lt;br /&gt;
==The General Schrödinger Equation==&lt;br /&gt;
&lt;br /&gt;
The general formulation of the Schrödinger Equation for a time-dependent system of non-relativistic particles in [//en.wikipedia.org/wiki/Bra–ket_notation Bra-Ket notation] is:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;i \hbar \frac{d}{d t}\vert\Psi(t)\rangle = \hat H\vert\Psi(t)\rangle&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Here &amp;lt;math&amp;gt;i = \sqrt{-1}&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Imaginary_unit imaginary unit]. &amp;lt;math&amp;gt;\hbar&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Planck_constant reduced Planck&#039;s constant]. &amp;lt;math&amp;gt;\vert\Psi(t)\rangle&amp;lt;/math&amp;gt; is the state vector of the quantum system at time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;, and &amp;lt;math&amp;gt;\hat H&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Hamiltonian_(quantum_mechanics) Hamiltonian operator]. For a single particle, the general Schrödinger Equation reduces to a single linear partial differential equation:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r},t)\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\Psi(\vec{r},t)&amp;lt;/math&amp;gt; becomes the wave function of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;. &amp;lt;math&amp;gt;V(\vec{r},t)&amp;lt;/math&amp;gt; is the scalar potential energy of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Time-independent Potential and Separation of Variables==&lt;br /&gt;
&lt;br /&gt;
The [[Potential Energy | potential energy]] of a system is often not an explicit function of time, that is &amp;lt;math&amp;gt;\frac{\partial V}{\partial t} = 0&amp;lt;/math&amp;gt;. Implying that, for such systems, the Schrödinger Equation of a single particle may be written as:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\frac{d}{d t}\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r})\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This, along with the [//en.wikipedia.org/wiki/Spectral_theorem spectral theorem] allows us to assume that the solution for this equation may be obtained through the separation of variables. That is, expressing the wave function as a product of a time-independent and a position-independent function:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) \equiv \psi(\vec{r})\phi(t) \rightarrow&lt;br /&gt;
i\hbar\frac{d}{d t}\psi(\vec{r})\phi(t) = - \frac{\hbar^2}{2m} \nabla ^2 \psi(\vec{r})\phi(t) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Expanding the derivatives through the [//en.wikipedia.org/wiki/Chain_rule chain rule] yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\psi(\vec{r})\frac{d}{d t}\phi(t) = - \frac{\hbar^2}{2m} \phi(t)\nabla ^2 \psi(\vec{r}) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dividing both sides of the equation by &amp;lt;math&amp;gt;\psi(\vec{r})\phi(t)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The left side of this equation is position-independent, and the right side of the equation is time-independent. Therefore, we have successfully [https://en.wikipedia.org/wiki/Separation_of_variables#Partial_differential_equations separated variables], allowing us to solve for &amp;lt;math&amp;gt;\phi(t)&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\psi(\vec{r})&amp;lt;/math&amp;gt; separatedely. Doing so yields:&lt;br /&gt;
&lt;br /&gt;

====Time-Independent Schrödinger Equation for 1 Particle====&lt;br /&gt;
&amp;lt;math&amp;gt;- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) + V(\vec{r})\psi(\vec{r})= E \psi(\vec{r})&amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours&amp;quot;&amp;gt;&lt;br /&gt;
====Space-Independent Schrödinger Equation for 1 Particle====&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{d}{d t}\phi(t)= -\frac{i}{\hbar}\left(E + V \right)\phi(t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A full derivation of this equations can be found below:&lt;br /&gt;
&lt;br /&gt;

====Derivation of the Time-Independent and Space-Independent Schrödinger Equation====&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
Start from the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Take the derivative of both sides in respect to time:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\left(&lt;br /&gt;
\frac{\ddot{\phi}}{\phi}&lt;br /&gt;
-\frac{\dot{\phi}^2}{\phi^2}&lt;br /&gt;
\right) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
From now on, for the sake of simplicity, [//en.wikipedia.org/wiki/Notation_for_differentiation#Newton&#039;s_notation Newton&#039;s Notation] will be used to express derivatives. Simplifying the equation above yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\ddot{\phi}\phi = \dot{\phi}^2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Treat &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; as an independent variable and define &amp;lt;math&amp;gt;v(\phi) = \dot{\phi}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d}{dt}\left(\dot{\phi}\right)\phi = \left( \dot{\phi}\right)^2&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{d}{dt}\left(v(\phi)\right)\phi = v^2(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By the chain rule:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt}\frac{dv}{d\phi}\phi = v^2(\phi) \rightarrow&lt;br /&gt;
\frac{dv}{d\phi}\phi = v(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writting in differential form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{dv}{v}=\frac{d\phi}{\phi}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Integrate both sides yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{dv}{v}=\int\frac{d\phi}{\phi}&lt;br /&gt;
        \rightarrow \ln{v} = \ln{\phi} + C_1&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solve for &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt; and simplify arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
v(\phi)=C_1\phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substitute in the definition of &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt} = C_1 \phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rewrite in differential form and integrate:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int \frac{d\phi}{\phi} = \int C_1 dt&lt;br /&gt;
\rightarrow&lt;br /&gt;
\ln{\phi} = C_1 t + C_2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; and simplifying arbitrary constants yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\phi(t) = C_2 e^{C_1 t}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the Schrödinger Equation yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
C_1 = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Therefore:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\dot{\phi}}{\phi} = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
\rightarrow&lt;br /&gt;
- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) + V(\vec{r})\psi(\vec{r})= E \psi(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Which is the Time-Independent Schrödinger Equation.&lt;br /&gt;
&lt;br /&gt;
::&lt;br /&gt;
&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==The Free Particle==&lt;br /&gt;
&lt;br /&gt;
The free particle is a special case of the Schrödinger Equation where the potential is null (or constant) everywhere in space:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
V(\vec{r},t) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This potential is time and space independent, therefore we may use the equations found in the section above:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) = A\psi(\vec{r})e^{-i\frac{E}{\hbar}t}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) = E \psi(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The latter is a form of the [//en.wikipedia.org/wiki/Helmholtz_equation Helmholtz Equation]. There is exists a general solution for an unbounded geometry in [//mathworld.wolfram.com/SphericalCoordinates.html Spherical Coordinates]:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\psi (r, \theta, \varphi)= \sum_{\ell=0}^\infty \sum_{n=-\ell}^\ell \left( a_{\ell n} j_\ell \left( \frac{\sqrt{2mE}}{\hbar} r \right) + b_{\ell n} y_\ell \left(\frac{\sqrt{2mE}}{\hbar}r\right) \right) Y^n_\ell(\theta,\varphi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Here &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\ell&amp;lt;/math&amp;gt; are quantum numbers. &amp;lt;math&amp;gt;a_{\ell n}&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;b_{\ell n}&amp;lt;/math&amp;gt; are amplitudes that define the wave packet. &amp;lt;math&amp;gt;j_\ell&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;y_\ell&amp;lt;/math&amp;gt; are the [//en.wikipedia.org/wiki/Bessel_function#Spherical_Bessel_functions spherical Bessel functions], and &amp;lt;math&amp;gt;Y^n_\ell(\theta,\varphi)&amp;lt;/math&amp;gt; are the [//en.wikipedia.org/wiki/Spherical_harmonics spherical harmonics].&lt;br /&gt;
&lt;br /&gt;
===General Solution in 1 Dimension===&lt;br /&gt;
&lt;br /&gt;
In one dimension our equation takes the form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
- \frac {\hbar^2}{2m} \frac{\partial^2\psi(x)}{\partial x^2} = E \psi(x)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Define &amp;lt;math&amp;gt;k^2 \equiv \frac{2mE}{\hbar^2}&amp;lt;/math&amp;gt; and rewrite:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\partial^2\psi(x)}{\partial x^2} = -k^2 \psi(x)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Assume &amp;lt;math&amp;gt;\psi&amp;lt;/math&amp;gt; as an independent variable, then define &amp;lt;math&amp;gt;v \equiv \frac{\partial\psi(x)}{\partial x}&amp;lt;/math&amp;gt;. Then:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\partial v}{\partial x} = -k^2 \psi \rightarrow&lt;br /&gt;
\frac{\partial v}{\partial \psi} \frac{\partial \psi}{\partial x}= -k^2 \psi&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{\partial v}{\partial \psi}v = - k^2\psi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rewrite in differential form and integrate:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int v \partial v = -k^2 \int \psi \partial \psi \rightarrow&lt;br /&gt;
\frac{v^2}{2}= -k^2\left(&lt;br /&gt;
\frac{\psi^2}{2} + C_1&lt;br /&gt;
\right)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;v&amp;lt;/math&amp;gt; and simplifying arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
v = \pm i k \sqrt{\psi^2 + C_1}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting the definition of &amp;lt;math&amp;gt;v&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\partial\psi(x)}{\partial x} = \pm i k \sqrt{\psi^2 + C_1}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writing in differential form and integrating:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{\partial\psi}{\sqrt{\psi^2 + C_1}} = \pm i k  \int \partial x&lt;br /&gt;
\rightarrow&lt;br /&gt;
\ln{\left(\psi + \sqrt{\psi^2+C_1}\right)}= \pm i k x + C_2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;\psi&amp;lt;/math&amp;gt; and simplifying arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\psi(x)= C_1 e^{ikx} + C_2 e^{-ikx}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Notice, however, that since &amp;lt;math&amp;gt;k&amp;lt;/math&amp;gt; is a function of the energy, this means a more general solution may be obtained by adding the contribution of many different energy levels:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\psi(x)= \sum_n A_n e^{i k_n x} + B_n e^{-ik_n x}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Furthermore it is possible to show that, if &amp;lt;math&amp;gt;\Psi(x,0)&amp;lt;/math&amp;gt; is known, then:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(x,t) = \sqrt{\frac{m}{2\pi\hbar i}\frac{1}{t}}\int_{-\infty}^{\infty}\psi\left(y\right)e^{-\frac{m}{2\hbar i}\frac{\left(x-y\right)^2}{t}}dy&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Claimed by Carlos M. Silva (Spring 2022)&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Schrödinger Equation is a [//en.wikipedia.org/wiki/Linear_differential_equation linear] [//en.wikipedia.org/wiki/Partial_differential_equation partial differential equation] that governs the [[Wave-Particle Duality | wave function]] of a [//en.wikipedia.org/wiki/Quantum_mechanics quantum mechanical system]&amp;lt;ref name=&amp;quot;Griffts Quantum&amp;quot;&amp;gt;Griffiths, David J. (2004). Introduction to Quantum Mechanics (2nd ed.). Prentice Hall. ISBN 978-0-13-111892-8.&amp;lt;/ref&amp;gt;. Similar to [[Newton&#039;s Second Law: the Momentum Principle | Newton&#039;s Laws]], the Schrödinger Equation is an equation of motion, meaning that it&#039;s capable of describing the time-evolution of a position analog of a system.&lt;br /&gt;
&lt;br /&gt;
The free particle is the name given to the system consisting of a single particle subject to a null or constant potential everywhere in space. It&#039;s the simplest system to which the Schrödinger Equation has a solution with physical meaning.&lt;br /&gt;
&lt;br /&gt;
Although the free-particle solution does not have ample practical use in the field of Physics, the methods and conclusions that come from the solution of this system are of great use in a plethora of other quantum systems.&lt;br /&gt;
&lt;br /&gt;
==The General Schrödinger Equation==&lt;br /&gt;
&lt;br /&gt;
The general formulation of the Schrödinger Equation for a time-dependent system of non-relativistic particles in [//en.wikipedia.org/wiki/Bra–ket_notation Bra-Ket notation] is:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;i \hbar \frac{d}{d t}\vert\Psi(t)\rangle = \hat H\vert\Psi(t)\rangle&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Here &amp;lt;math&amp;gt;i = \sqrt{-1}&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Imaginary_unit imaginary unit]. &amp;lt;math&amp;gt;\hbar&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Planck_constant reduced Planck&#039;s constant]. &amp;lt;math&amp;gt;\vert\Psi(t)\rangle&amp;lt;/math&amp;gt; is the state vector of the quantum system at time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;, and &amp;lt;math&amp;gt;\hat H&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Hamiltonian_(quantum_mechanics) Hamiltonian operator]. For a single particle, the general Schrödinger Equation reduces to a single linear partial differential equation:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r},t)\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\Psi(\vec{r},t)&amp;lt;/math&amp;gt; becomes the wave function of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;. &amp;lt;math&amp;gt;V(\vec{r},t)&amp;lt;/math&amp;gt; is the scalar potential energy of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Time-independent Potential and Separation of Variables==&lt;br /&gt;
&lt;br /&gt;
The [[Potential Energy | potential energy]] of a system is often not an explicit function of time, that is &amp;lt;math&amp;gt;\frac{\partial V}{\partial t} = 0&amp;lt;/math&amp;gt;. Implying that, for such systems, the Schrödinger Equation of a single particle may be written as:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\frac{d}{d t}\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r})\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This, along with the [//en.wikipedia.org/wiki/Spectral_theorem spectral theorem] allows us to assume that the solution for this equation may be obtained through the separation of variables. That is, expressing the wave function as a product of a time-independent and a position-independent function:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) \equiv \psi(\vec{r})\phi(t) \rightarrow&lt;br /&gt;
i\hbar\frac{d}{d t}\psi(\vec{r})\phi(t) = - \frac{\hbar^2}{2m} \nabla ^2 \psi(\vec{r})\phi(t) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Expanding the derivatives through the [//en.wikipedia.org/wiki/Chain_rule chain rule] yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\psi(\vec{r})\frac{d}{d t}\phi(t) = - \frac{\hbar^2}{2m} \phi(t)\nabla ^2 \psi(\vec{r}) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dividing both sides of the equation by &amp;lt;math&amp;gt;\psi(\vec{r})\phi(t)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The left side of this equation is position-independent, and the right side of the equation is time-independent. Therefore, we have successfully [https://en.wikipedia.org/wiki/Separation_of_variables#Partial_differential_equations separated variables], allowing us to solve for &amp;lt;math&amp;gt;\phi(t)&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\psi(\vec{r})&amp;lt;/math&amp;gt; separatedely. Doing so yields:&lt;br /&gt;

&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;

====Derivation of the Time-Independent and Space-Independent Schrödinger Equation====&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
Start from the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Take the derivative of both sides in respect to time:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\left(&lt;br /&gt;
\frac{\ddot{\phi}}{\phi}&lt;br /&gt;
-\frac{\dot{\phi}^2}{\phi^2}&lt;br /&gt;
\right) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
From now on, for the sake of simplicity, [//en.wikipedia.org/wiki/Notation_for_differentiation#Newton&#039;s_notation Newton&#039;s Notation] will be used to express derivatives. Simplifying the equation above yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\ddot{\phi}\phi = \dot{\phi}^2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Treat &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; as an independent variable and define &amp;lt;math&amp;gt;v(\phi) = \dot{\phi}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d}{dt}\left(\dot{\phi}\right)\phi = \left( \dot{\phi}\right)^2&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{d}{dt}\left(v(\phi)\right)\phi = v^2(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By the chain rule:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt}\frac{dv}{d\phi}\phi = v^2(\phi) \rightarrow&lt;br /&gt;
\frac{dv}{d\phi}\phi = v(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writting in differential form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{dv}{v}=\frac{d\phi}{\phi}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Integrate both sides yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{dv}{v}=\int\frac{d\phi}{\phi}&lt;br /&gt;
        \rightarrow \ln{v} = \ln{\phi} + C_1&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solve for &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt; and simplify arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
v(\phi)=C_1\phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substitute in the definition of &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt} = C_1 \phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rewrite in differential form and integrate:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int \frac{d\phi}{\phi} = \int C_1 dt&lt;br /&gt;
\rightarrow&lt;br /&gt;
\ln{\phi} = C_1 t + C_2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; and simplifying arbitrary constants yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\phi(t) = C_2 e^{C_1 t}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the Schrödinger Equation yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
C_1 = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Therefore:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\dot{\phi}}{\phi} = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
\rightarrow&lt;br /&gt;
- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) + V(\vec{r})\psi(\vec{r})= E \psi(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Which is the Time-Independent Schrödinger Equation.&lt;br /&gt;
&lt;br /&gt;
::&lt;br /&gt;
&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==The Free Particle==&lt;br /&gt;
&lt;br /&gt;
The free particle is a special case of the Schrödinger Equation where the potential is null (or constant) everywhere in space:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
V(\vec{r},t) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This potential is time and space independent, therefore we may use the equations found in the section above:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) = A\psi(\vec{r})e^{-i\frac{E}{\hbar}t}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) = E \psi(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The latter is a form of the [//en.wikipedia.org/wiki/Helmholtz_equation Helmholtz Equation]. There is exists a general solution for an unbounded geometry in [//mathworld.wolfram.com/SphericalCoordinates.html Spherical Coordinates]:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\psi (r, \theta, \varphi)= \sum_{\ell=0}^\infty \sum_{n=-\ell}^\ell \left( a_{\ell n} j_\ell \left( \frac{\sqrt{2mE}}{\hbar} r \right) + b_{\ell n} y_\ell \left(\frac{\sqrt{2mE}}{\hbar}r\right) \right) Y^n_\ell(\theta,\varphi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Here &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\ell&amp;lt;/math&amp;gt; are quantum numbers. &amp;lt;math&amp;gt;a_{\ell n}&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;b_{\ell n}&amp;lt;/math&amp;gt; are amplitudes that define the wave packet. &amp;lt;math&amp;gt;j_\ell&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;y_\ell&amp;lt;/math&amp;gt; are the [//en.wikipedia.org/wiki/Bessel_function#Spherical_Bessel_functions spherical Bessel functions], and &amp;lt;math&amp;gt;Y^n_\ell(\theta,\varphi)&amp;lt;/math&amp;gt; are the [//en.wikipedia.org/wiki/Spherical_harmonics spherical harmonics].&lt;br /&gt;
&lt;br /&gt;
===General Solution in 1 Dimension===&lt;br /&gt;
&lt;br /&gt;
In one dimension our equation takes the form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
- \frac {\hbar^2}{2m} \frac{\partial^2\psi(x)}{\partial x^2} = E \psi(x)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Claimed by Carlos M. Silva (Spring 2022)&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Schrödinger Equation is a [//en.wikipedia.org/wiki/Linear_differential_equation linear] [//en.wikipedia.org/wiki/Partial_differential_equation partial differential equation] that governs the [[Wave-Particle Duality | wave function]] of a [//en.wikipedia.org/wiki/Quantum_mechanics quantum mechanical system]&amp;lt;ref name=&amp;quot;Griffts Quantum&amp;quot;&amp;gt;Griffiths, David J. (2004). Introduction to Quantum Mechanics (2nd ed.). Prentice Hall. ISBN 978-0-13-111892-8.&amp;lt;/ref&amp;gt;. Similar to [[Newton&#039;s Second Law: the Momentum Principle | Newton&#039;s Laws]], the Schrödinger Equation is an equation of motion, meaning that it&#039;s capable of describing the time-evolution of a position analog of a system.&lt;br /&gt;
&lt;br /&gt;
The free particle is the name given to the system consisting of a single particle subject to a null or constant potential everywhere in space. It&#039;s the simplest system to which the Schrödinger Equation has a solution with physical meaning.&lt;br /&gt;
&lt;br /&gt;
Although the free-particle solution does not have ample practical use in the field of Physics, the methods and conclusions that come from the solution of this system are of great use in a plethora of other quantum systems.&lt;br /&gt;
&lt;br /&gt;
==The General Schrödinger Equation==&lt;br /&gt;
&lt;br /&gt;
The general formulation of the Schrödinger Equation for a time-dependent system of non-relativistic particles in [//en.wikipedia.org/wiki/Bra–ket_notation Bra-Ket notation] is:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;i \hbar \frac{d}{d t}\vert\Psi(t)\rangle = \hat H\vert\Psi(t)\rangle&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Here &amp;lt;math&amp;gt;i = \sqrt{-1}&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Imaginary_unit imaginary unit]. &amp;lt;math&amp;gt;\hbar&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Planck_constant reduced Planck&#039;s constant]. &amp;lt;math&amp;gt;\vert\Psi(t)\rangle&amp;lt;/math&amp;gt; is the state vector of the quantum system at time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;, and &amp;lt;math&amp;gt;\hat H&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Hamiltonian_(quantum_mechanics) Hamiltonian operator]. For a single particle, the general Schrödinger Equation reduces to a single linear partial differential equation:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r},t)\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\Psi(\vec{r},t)&amp;lt;/math&amp;gt; becomes the wave function of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;. &amp;lt;math&amp;gt;V(\vec{r},t)&amp;lt;/math&amp;gt; is the scalar potential energy of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Time-independent Potential and Separation of Variables==&lt;br /&gt;
&lt;br /&gt;
The [[Potential Energy | potential energy]] of a system is often not an explicit function of time, that is &amp;lt;math&amp;gt;\frac{\partial V}{\partial t} = 0&amp;lt;/math&amp;gt;. Implying that, for such systems, the Schrödinger Equation of a single particle may be written as:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\frac{d}{d t}\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r})\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This, along with the [//en.wikipedia.org/wiki/Spectral_theorem spectral theorem] allows us to assume that the solution for this equation may be obtained through the separation of variables. That is, expressing the wave function as a product of a time-independent and a position-independent function:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) \equiv \psi(\vec{r})\phi(t) \rightarrow&lt;br /&gt;
i\hbar\frac{d}{d t}\psi(\vec{r})\phi(t) = - \frac{\hbar^2}{2m} \nabla ^2 \psi(\vec{r})\phi(t) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Expanding the derivatives through the [//en.wikipedia.org/wiki/Chain_rule chain rule] yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\psi(\vec{r})\frac{d}{d t}\phi(t) = - \frac{\hbar^2}{2m} \phi(t)\nabla ^2 \psi(\vec{r}) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dividing both sides of the equation by &amp;lt;math&amp;gt;\psi(\vec{r})\phi(t)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The left side of this equation is position-independent, and the right side of the equation is time-independent. Therefore, we have successfully [https://en.wikipedia.org/wiki/Separation_of_variables#Partial_differential_equations separated variables], allowing us to solve for &amp;lt;math&amp;gt;\phi(t)&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\psi(\vec{r})&amp;lt;/math&amp;gt; separatedely.

====Derivation of the Time-Independent and Space-Independent Schrödinger Equation====&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
Start from the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Take the derivative of both sides in respect to time:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\left(&lt;br /&gt;
\frac{\ddot{\phi}}{\phi}&lt;br /&gt;
-\frac{\dot{\phi}^2}{\phi^2}&lt;br /&gt;
\right) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
From now on, for the sake of simplicity, [//en.wikipedia.org/wiki/Notation_for_differentiation#Newton&#039;s_notation Newton&#039;s Notation] will be used to express derivatives. Simplifying the equation above yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\ddot{\phi}\phi = \dot{\phi}^2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Treat &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; as an independent variable and define &amp;lt;math&amp;gt;v(\phi) = \dot{\phi}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d}{dt}\left(\dot{\phi}\right)\phi = \left( \dot{\phi}\right)^2&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{d}{dt}\left(v(\phi)\right)\phi = v^2(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By the chain rule:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt}\frac{dv}{d\phi}\phi = v^2(\phi) \rightarrow&lt;br /&gt;
\frac{dv}{d\phi}\phi = v(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writting in differential form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{dv}{v}=\frac{d\phi}{\phi}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Integrate both sides yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{dv}{v}=\int\frac{d\phi}{\phi}&lt;br /&gt;
        \rightarrow \ln{v} = \ln{\phi} + C_1&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solve for &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt; and simplify arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
v(\phi)=C_1\phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substitute in the definition of &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt} = C_1 \phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rewrite in differential form and integrate:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int \frac{d\phi}{\phi} = \int C_1 dt&lt;br /&gt;
\rightarrow&lt;br /&gt;
\ln{\phi} = C_1 t + C_2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; and simplifying arbitrary constants yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\phi(t) = C_2 e^{C_1 t}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the Schrödinger Equation yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
C_1 = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Therefore:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\dot{\phi}}{\phi} = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
\rightarrow&lt;br /&gt;
- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) + V(\vec{r})\psi(\vec{r})= E \psi(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Which is the Time-Independent Schrödinger Equation.&lt;br /&gt;
&lt;br /&gt;
::&lt;br /&gt;
&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==The Free Particle==&lt;br /&gt;
&lt;br /&gt;
The free particle is a special case of the Schrödinger Equation where the potential is null (or constant) everywhere in space:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
V(\vec{r},t) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;&#039;&#039;&#039;Claimed by Carlos M. Silva (Spring 2022)&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Schrödinger Equation is a [//en.wikipedia.org/wiki/Linear_differential_equation linear] [//en.wikipedia.org/wiki/Partial_differential_equation partial differential equation] that governs the [[Wave-Particle Duality | wave function]] of a [//en.wikipedia.org/wiki/Quantum_mechanics quantum mechanical system]&amp;lt;ref name=&amp;quot;Griffts Quantum&amp;quot;&amp;gt;Griffiths, David J. (2004). Introduction to Quantum Mechanics (2nd ed.). Prentice Hall. ISBN 978-0-13-111892-8.&amp;lt;/ref&amp;gt;. Similar to [[Newton&#039;s Second Law: the Momentum Principle | Newton&#039;s Laws]], the Schrödinger Equation is an equation of motion, meaning that it&#039;s capable of describing the time-evolution of a position analog of a system.&lt;br /&gt;
&lt;br /&gt;
The free particle is the name given to the system consisting of a single particle subject to a null or constant potential everywhere in space. It&#039;s the simplest system to which the Schrödinger Equation has a solution with physical meaning.&lt;br /&gt;
&lt;br /&gt;
Although the free-particle solution does not have ample practical use in the field of Physics, the methods and conclusions that come from the solution of this system are of great use in a plethora of other quantum systems.&lt;br /&gt;
&lt;br /&gt;
==The General Schrödinger Equation==&lt;br /&gt;
&lt;br /&gt;
The general formulation of the Schrödinger Equation for a time-dependent system of non-relativistic particles in [//en.wikipedia.org/wiki/Bra–ket_notation Bra-Ket notation] is:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;i \hbar \frac{d}{d t}\vert\Psi(t)\rangle = \hat H\vert\Psi(t)\rangle&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Here &amp;lt;math&amp;gt;i = \sqrt{-1}&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Imaginary_unit imaginary unit]. &amp;lt;math&amp;gt;\hbar&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Planck_constant reduced Planck&#039;s constant]. &amp;lt;math&amp;gt;\vert\Psi(t)\rangle&amp;lt;/math&amp;gt; is the state vector of the quantum system at time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;, and &amp;lt;math&amp;gt;\hat H&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Hamiltonian_(quantum_mechanics) Hamiltonian operator]. For a single particle, the general Schrödinger Equation reduces to a single linear partial differential equation:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r},t)\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\Psi(\vec{r},t)&amp;lt;/math&amp;gt; becomes the wave function of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;. &amp;lt;math&amp;gt;V(\vec{r},t)&amp;lt;/math&amp;gt; is the scalar potential energy of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Time-independent Potential and Separation of Variables==&lt;br /&gt;
&lt;br /&gt;
The [[Potential Energy | potential energy]] of a system is often not an explicit function of time, that is &amp;lt;math&amp;gt;\frac{\partial V}{\partial t} = 0&amp;lt;/math&amp;gt;. Implying that, for such systems, the Schrödinger Equation of a single particle may be written as:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\frac{d}{d t}\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r})\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This, along with the [//en.wikipedia.org/wiki/Spectral_theorem spectral theorem] allows us to assume that the solution for this equation may be obtained through the separation of variables. That is, expressing the wave function as a product of a time-independent and a position-independent function:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) \equiv \psi(\vec{r})\phi(t) \rightarrow&lt;br /&gt;
i\hbar\frac{d}{d t}\psi(\vec{r})\phi(t) = - \frac{\hbar^2}{2m} \nabla ^2 \psi(\vec{r})\phi(t) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Expanding the derivatives through the [//en.wikipedia.org/wiki/Chain_rule chain rule] yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\psi(\vec{r})\frac{d}{d t}\phi(t) = - \frac{\hbar^2}{2m} \phi(t)\nabla ^2 \psi(\vec{r}) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dividing both sides of the equation by &amp;lt;math&amp;gt;\psi(\vec{r})\phi(t)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The left side of this equation is position-independent, and the right side of the equation is time-independent. Therefore, we have successfully [https://en.wikipedia.org/wiki/Separation_of_variables#Partial_differential_equations separated variables], allowing us to solve for &amp;lt;math&amp;gt;\phi(t)&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\psi(\vec{r})&amp;lt;/math&amp;gt; separatedely. Doing so yields:&lt;br /&gt;

====Time-Independent Schrödinger Equation for 1 Particle====&lt;br /&gt;
&amp;lt;math&amp;gt;- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) + V(\vec{r})\psi(\vec{r})= E \psi(\vec{r})&amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours&amp;quot;&amp;gt;&lt;br /&gt;
====Space-Independent Schrödinger Equation for 1 Particle====&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{d}{d t}\phi(t)= -\frac{i}{\hbar}\left(E + V \right)\phi(t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A full derivation of this equations can be found below:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours mw-collapsible mw-collapsed&amp;quot;&amp;gt;&lt;br /&gt;
====Derivation of the Time-Independent and Space-Independent Schrödinger Equation====&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
Start from the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Take the derivative of both sides in respect to time:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\left(&lt;br /&gt;
\frac{\ddot{\phi}}{\phi}&lt;br /&gt;
-\frac{\dot{\phi}^2}{\phi^2}&lt;br /&gt;
\right) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
From now on, for the sake of simplicity, [//en.wikipedia.org/wiki/Notation_for_differentiation#Newton&#039;s_notation Newton&#039;s Notation] will be used to express derivatives. Simplifying the equation above yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\ddot{\phi}\phi = \dot{\phi}^2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Treat &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; as an independent variable and define &amp;lt;math&amp;gt;v(\phi) = \dot{\phi}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d}{dt}\left(\dot{\phi}\right)\phi = \left( \dot{\phi}\right)^2&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{d}{dt}\left(v(\phi)\right)\phi = v^2(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By the chain rule:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt}\frac{dv}{d\phi}\phi = v^2(\phi) \rightarrow&lt;br /&gt;
\frac{dv}{d\phi}\phi = v(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writting in differential form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{dv}{v}=\frac{d\phi}{\phi}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Integrate both sides yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{dv}{v}=\int\frac{d\phi}{\phi}&lt;br /&gt;
        \rightarrow \ln{v} = \ln{\phi} + C_1&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solve for &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt; and simplify arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
v(\phi)=C_1\phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substitute in the definition of &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt} = C_1 \phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rewrite in differential form and integrate:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int \frac{d\phi}{\phi} = \int C_1 dt&lt;br /&gt;
\rightarrow&lt;br /&gt;
\ln{\phi} = C_1 t + C_2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; and simplifying arbitrary constants yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\phi(t) = C_2 e^{C_1 t}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the Schrödinger Equation yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
C_1 = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Therefore:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\dot{\phi}}{\phi} = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
\rightarrow&lt;br /&gt;
- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) + V(\vec{r})\psi(\vec{r})= E \psi(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Which is the Time-Independent Schrödinger Equation.&lt;br /&gt;
&lt;br /&gt;
::&lt;br /&gt;
&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;

For a single particle, the general Schrödinger Equation reduces to a single linear partial differential equation:&lt;br /&gt;

&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\Psi(\vec{r},t)&amp;lt;/math&amp;gt; becomes the wave function of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;. &amp;lt;math&amp;gt;V(\vec{r},t)&amp;lt;/math&amp;gt; is the scalar potential energy of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;.&lt;br /&gt;

Dividing both sides of the equation by &amp;lt;math&amp;gt;\psi(\vec{r})\phi(t)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The left side of this equation is position-independent, and the right side of the equation is time-independent. Therefore, we have successfully [https://en.wikipedia.org/wiki/Separation_of_variables#Partial_differential_equations separated variables], allowing us to solve for &amp;lt;math&amp;gt;\phi(t)&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\psi(\vec{r})&amp;lt;/math&amp;gt; separatedely. Doing so yields:&lt;br /&gt;

&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;

====Derivation of the Time-Independent and Space-Independent Schrödinger Equation====&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
Start from the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Take the derivative of both sides in respect to time:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\left(&lt;br /&gt;
\frac{\ddot{\phi}}{\phi}&lt;br /&gt;
-\frac{\dot{\phi}^2}{\phi^2}&lt;br /&gt;
\right) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
From now on, for the sake of simplicity, [//en.wikipedia.org/wiki/Notation_for_differentiation#Newton&#039;s_notation Newton&#039;s Notation] will be used to express derivatives. Simplifying the equation above yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\ddot{\phi}\phi = \dot{\phi}^2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Treat &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; as an independent variable and define &amp;lt;math&amp;gt;v(\phi) = \dot{\phi}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d}{dt}\left(\dot{\phi}\right)\phi = \left( \dot{\phi}\right)^2&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{d}{dt}\left(v(\phi)\right)\phi = v^2(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By the chain rule:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt}\frac{dv}{d\phi}\phi = v^2(\phi) \rightarrow&lt;br /&gt;
\frac{dv}{d\phi}\phi = v(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writting in differential form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{dv}{v}=\frac{d\phi}{\phi}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Integrate both sides yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{dv}{v}=\int\frac{d\phi}{\phi}&lt;br /&gt;
        \rightarrow \ln{v} = \ln{\phi} + C_1&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solve for &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt; and simplify arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
v(\phi)=C_1\phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substitute in the definition of &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt} = C_1 \phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rewrite in differential form and integrate:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int \frac{d\phi}{\phi} = \int C_1 dt&lt;br /&gt;
\rightarrow&lt;br /&gt;
\ln{\phi} = C_1 t + C_2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; and simplifying arbitrary constants yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\phi(t) = C_2 e^{C_1 t}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the Schrödinger Equation yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
C_1 = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Therefore:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{\dot{\phi}}{\phi} = -i\frac{E+V}{\hbar}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substituting this relation back in the the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) + V(\vec{r})\psi(\vec{r})= E \psi(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Which is the Time-Independent Schrödinger Equation.&lt;br /&gt;
&lt;br /&gt;
::&lt;br /&gt;
&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;&#039;&#039;&#039;Claimed by Carlos M. Silva (Spring 2022)&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Schrödinger Equation is a [//en.wikipedia.org/wiki/Linear_differential_equation linear] [//en.wikipedia.org/wiki/Partial_differential_equation partial differential equation] that governs the [[Wave-Particle Duality | wave function]] of a [//en.wikipedia.org/wiki/Quantum_mechanics quantum mechanical system]&amp;lt;ref name=&amp;quot;Griffts Quantum&amp;quot;&amp;gt;Griffiths, David J. (2004). Introduction to Quantum Mechanics (2nd ed.). Prentice Hall. ISBN 978-0-13-111892-8.&amp;lt;/ref&amp;gt;. Similar to [[Newton&#039;s Second Law: the Momentum Principle | Newton&#039;s Laws]], the Schrödinger Equation is an equation of motion, meaning that it&#039;s capable of describing the time-evolution of a position analog of a system.&lt;br /&gt;
&lt;br /&gt;
The free particle is the name given to the system consisting of a single particle subject to a null or constant potential everywhere in space. It&#039;s the simplest system to which the Schrödinger Equation has a solution with physical meaning.&lt;br /&gt;
&lt;br /&gt;
Although the free-particle solution does not have ample practical use in the field of Physics, the methods and conclusions that come from the solution of this system are of great use in a plethora of other quantum systems.&lt;br /&gt;
&lt;br /&gt;
==The General Schrödinger Equation==&lt;br /&gt;
&lt;br /&gt;
The general formulation of the Schrödinger Equation for a time-dependent system of non-relativistic particles in [//en.wikipedia.org/wiki/Bra–ket_notation Bra-Ket notation] is:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;i \hbar \frac{d}{d t}\vert\Psi(t)\rangle = \hat H\vert\Psi(t)\rangle&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Here &amp;lt;math&amp;gt;i = \sqrt{-1}&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Imaginary_unit imaginary unit]. &amp;lt;math&amp;gt;\hbar&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Planck_constant reduced Planck&#039;s constant]. &amp;lt;math&amp;gt;\vert\Psi(t)\rangle&amp;lt;/math&amp;gt; is the state vector of the quantum system at time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;, and &amp;lt;math&amp;gt;\hat H&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Hamiltonian_(quantum_mechanics) Hamiltonian operator]. For a single particle, the general Schrödinger Equation reduces to a single linear partial differential equation:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r},t)\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\Psi(\vec{r},t)&amp;lt;/math&amp;gt; becomes the wave function of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;. &amp;lt;math&amp;gt;V(\vec{r},t)&amp;lt;/math&amp;gt; is the scalar potential energy of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Time-independent Potential and Separation of Variables==&lt;br /&gt;
&lt;br /&gt;
The [[Potential Energy | potential energy]] of a system is often not an explicit function of time, that is &amp;lt;math&amp;gt;\frac{\partial V}{\partial t} = 0&amp;lt;/math&amp;gt;. Implying that, for such systems, the Schrödinger Equation of a single particle may be written as:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\frac{d}{d t}\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r})\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This, along with the [//en.wikipedia.org/wiki/Spectral_theorem spectral theorem] allows us to assume that the solution for this equation may be obtained through the separation of variables. That is, expressing the wave function as a product of a time-independent and a position-independent function:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) \equiv \psi(\vec{r})\phi(t) \rightarrow&lt;br /&gt;
i\hbar\frac{d}{d t}\psi(\vec{r})\phi(t) = - \frac{\hbar^2}{2m} \nabla ^2 \psi(\vec{r})\phi(t) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Expanding the derivatives through the [//en.wikipedia.org/wiki/Chain_rule chain rule] yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\psi(\vec{r})\frac{d}{d t}\phi(t) = - \frac{\hbar^2}{2m} \phi(t)\nabla ^2 \psi(\vec{r}) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dividing both sides of the equation by &amp;lt;math&amp;gt;\psi(\vec{r})\phi(t)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The left side of this equation is position-independent, and the right side of the equation is time-independent. Therefore, we have successfully [https://en.wikipedia.org/wiki/Separation_of_variables#Partial_differential_equations separated variables], allowing us to solve for &amp;lt;math&amp;gt;\phi(t)&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\psi(\vec{r})&amp;lt;/math&amp;gt; separatedely. Doing so yields:&lt;br /&gt;

&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A full derivation of this equations can be found below:&lt;br /&gt;

====Derivation of the Time-Independent and Space-Independent Schrödinger Equation====&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
Start from the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Take the derivative of both sides in respect to time:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\left(&lt;br /&gt;
\frac{\ddot{\phi}}{\phi}&lt;br /&gt;
-\frac{\dot{\phi}^2}{\phi^2}&lt;br /&gt;
\right) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
From now on, for the sake of simplicity, [//en.wikipedia.org/wiki/Notation_for_differentiation#Newton&#039;s_notation Newton&#039;s Notation] will be used to express derivatives. Simplifying the equation above yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\ddot{\phi}\phi = \dot{\phi}^2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Treat &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; as an independent variable and define &amp;lt;math&amp;gt;v(\phi) = \dot{\phi}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d}{dt}\left(\dot{\phi}\right)\phi = \left( \dot{\phi}\right)^2&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{d}{dt}\left(v(\phi)\right)\phi = v^2(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By the chain rule:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt}\frac{dv}{d\phi}\phi = v^2(\phi) \rightarrow&lt;br /&gt;
\frac{dv}{d\phi}\phi = v(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writting in differential form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{dv}{v}=\frac{d\phi}{\phi}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Integrate both sides yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{dv}{v}=\int\frac{d\phi}{\phi}&lt;br /&gt;
        \rightarrow \ln{v} = \ln{\phi} + C_1&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solve for &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt; and simplify arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
v(\phi)=C_1\phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substitute in the definition of &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt} = C_1 \phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rewrite in differential form and integrate:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int \frac{d\phi}{\phi} = \int C_1 dt&lt;br /&gt;
\rightarrow&lt;br /&gt;
\ln{\phi} = C_1 t + C_2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; and simplifying arbitrary constants yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\phi(t) = C_2 e^{C_1 t}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
Here &amp;lt;math&amp;gt;i = \sqrt{-1}&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Imaginary_unit imaginary unit]. &amp;lt;math&amp;gt;\hbar&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Planck_constant reduced Planck&#039;s constant]. &amp;lt;math&amp;gt;\vert\Psi(t)\rangle&amp;lt;/math&amp;gt; is the state vector of the quantum system at time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;, and &amp;lt;math&amp;gt;\hat H&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Hamiltonian_(quantum_mechanics) Hamiltonian operator]. For a single particle, the general Schrödinger Equation reduces to a single linear partial differential equation:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r},t)\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\Psi(\vec{r},t)&amp;lt;/math&amp;gt; becomes the wave function of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;. &amp;lt;math&amp;gt;V(\vec{r},t)&amp;lt;/math&amp;gt; is the scalar potential energy of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Time-independent Potential and Separation of Variables==&lt;br /&gt;
&lt;br /&gt;
The [[Potential Energy | potential energy]] of a system is often not an explicit function of time, that is &amp;lt;math&amp;gt;\frac{\partial V}{\partial t} = 0&amp;lt;/math&amp;gt;. Implying that, for such systems, the Schrödinger Equation of a single particle may be written as:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\frac{d}{d t}\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r})\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This, along with the [//en.wikipedia.org/wiki/Spectral_theorem spectral theorem] allows us to assume that the solution for this equation may be obtained through the separation of variables. That is, expressing the wave function as a product of a time-independent and a position-independent function:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) \equiv \psi(\vec{r})\phi(t) \rightarrow&lt;br /&gt;
i\hbar\frac{d}{d t}\psi(\vec{r})\phi(t) = - \frac{\hbar^2}{2m} \nabla ^2 \psi(\vec{r})\phi(t) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Expanding the derivatives through the [//en.wikipedia.org/wiki/Chain_rule chain rule] yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\psi(\vec{r})\frac{d}{d t}\phi(t) = - \frac{\hbar^2}{2m} \phi(t)\nabla ^2 \psi(\vec{r}) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dividing both sides of the equation by &amp;lt;math&amp;gt;\psi(\vec{r})\phi(t)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The left side of this equation is position-independent, and the right side of the equation is time-independent. Therefore, we have successfully [https://en.wikipedia.org/wiki/Separation_of_variables#Partial_differential_equations separated variables], allowing us to solve for &amp;lt;math&amp;gt;\phi(t)&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\psi(\vec{r})&amp;lt;/math&amp;gt; separatedely. Doing so yields:&lt;br /&gt;

&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;

====Derivation of the Time-Independent and Space-Independent Schrödinger Equation====&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
Start from the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Take the derivative of both sides in respect to time:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\left(&lt;br /&gt;
\frac{\ddot{\phi}}{\phi}&lt;br /&gt;
-\frac{\dot{\phi}^2}{\phi^2}&lt;br /&gt;
\right) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
From now on, for the sake of simplicity, [//en.wikipedia.org/wiki/Notation_for_differentiation#Newton&#039;s_notation Newton&#039;s Notation] will be used to express derivatives. Simplifying the equation above yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\ddot{\phi}\phi = \dot{\phi}^2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Treat &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; as an independent variable and define &amp;lt;math&amp;gt;v(\phi) = \dot{\phi}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d}{dt}\left(\dot{\phi}\right)\phi = \left( \dot{\phi}\right)^2 \rightarrow&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{d}{dt}\left(v(\phi)\right)\phi = v^2(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By the chain rule:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt}\frac{dv}{d\phi}\phi = v^2(\phi) \rightarrow&lt;br /&gt;
\frac{dv}{d\phi}\phi = v(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writting in differential form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{dv}{v}=\frac{d\phi}{\phi}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Integrate both sides yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{dv}{v}=\int\frac{d\phi}{\phi}&lt;br /&gt;
        \rightarrow \ln{v} = \ln{\phi} + C_1&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solve for &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt; and simplify arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
v(\phi)=C_1\phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substitute in the definition of &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt} = C_1 \phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rewrite in differential form and integrate:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int \frac{d\phi}{\phi} = \int C_1 dt&lt;br /&gt;
\rightarrow&lt;br /&gt;
\ln{\phi} = C_1 t + C_2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; and simplifying arbitrary constants yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\phi(t) = C_2 e^{C_1 t}&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;&#039;&#039;&#039;Claimed by Carlos M. Silva (Spring 2022)&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The Schrödinger Equation is a [//en.wikipedia.org/wiki/Linear_differential_equation linear] [//en.wikipedia.org/wiki/Partial_differential_equation partial differential equation] that governs the [[Wave-Particle Duality | wave function]] of a [//en.wikipedia.org/wiki/Quantum_mechanics quantum mechanical system]&amp;lt;ref name=&amp;quot;Griffts Quantum&amp;quot;&amp;gt;Griffiths, David J. (2004). Introduction to Quantum Mechanics (2nd ed.). Prentice Hall. ISBN 978-0-13-111892-8.&amp;lt;/ref&amp;gt;. Similar to [[Newton&#039;s Second Law: the Momentum Principle | Newton&#039;s Laws]], the Schrödinger Equation is an equation of motion, meaning that it&#039;s capable of describing the time-evolution of a position analog of a system.&lt;br /&gt;
&lt;br /&gt;
The free particle is the name given to the system consisting of a single particle subject to a null or constant potential everywhere in space. It&#039;s the simplest system to which the Schrödinger Equation has a solution with physical meaning.&lt;br /&gt;
&lt;br /&gt;
Although the free-particle solution does not have ample practical use in the field of Physics, the methods and conclusions that come from the solution of this system are of great use in a plethora of other quantum systems.&lt;br /&gt;
&lt;br /&gt;
==The General Schrödinger Equation==&lt;br /&gt;
&lt;br /&gt;
The general formulation of the Schrödinger Equation for a time-dependent system of non-relativistic particles in [//en.wikipedia.org/wiki/Bra–ket_notation Bra-Ket notation] is:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;i \hbar \frac{d}{d t}\vert\Psi(t)\rangle = \hat H\vert\Psi(t)\rangle&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Here &amp;lt;math&amp;gt;i = \sqrt{-1}&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Imaginary_unit imaginary unit]. &amp;lt;math&amp;gt;\hbar&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Planck_constant reduced Planck&#039;s constant]. &amp;lt;math&amp;gt;\vert\Psi(t)\rangle&amp;lt;/math&amp;gt; is the state vector of the quantum system at time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;, and &amp;lt;math&amp;gt;\hat H&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Hamiltonian_(quantum_mechanics) Hamiltonian operator]. For a single particle, the general Schrödinger Equation reduces to a single linear partial differential equation:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r},t)\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\Psi(\vec{r},t)&amp;lt;/math&amp;gt; becomes the wave function of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;. &amp;lt;math&amp;gt;V(\vec{r},t)&amp;lt;/math&amp;gt; is the scalar potential energy of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Time-independent Potential and Separation of Variables==&lt;br /&gt;
&lt;br /&gt;
The [[Potential Energy | potential energy]] of a system is often not an explicit function of time, that is &amp;lt;math&amp;gt;\frac{\partial V}{\partial t} = 0&amp;lt;/math&amp;gt;. Implying that, for such systems, the Schrödinger Equation of a single particle may be written as:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\frac{d}{d t}\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r})\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This, along with the [//en.wikipedia.org/wiki/Spectral_theorem spectral theorem] allows us to assume that the solution for this equation may be obtained through the separation of variables. That is, expressing the wave function as a product of a time-independent and a position-independent function:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) \equiv \psi(\vec{r})\phi(t) \rightarrow&lt;br /&gt;
i\hbar\frac{d}{d t}\psi(\vec{r})\phi(t) = - \frac{\hbar^2}{2m} \nabla ^2 \psi(\vec{r})\phi(t) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Expanding the derivatives through the [//en.wikipedia.org/wiki/Chain_rule chain rule] yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\psi(\vec{r})\frac{d}{d t}\phi(t) = - \frac{\hbar^2}{2m} \phi(t)\nabla ^2 \psi(\vec{r}) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dividing both sides of the equation by &amp;lt;math&amp;gt;\psi(\vec{r})\phi(t)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The left side of this equation is position-independent, and the right side of the equation is time-independent. Therefore, we have successfully [https://en.wikipedia.org/wiki/Separation_of_variables#Partial_differential_equations separated variables], allowing us to solve for &amp;lt;math&amp;gt;\phi(t)&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\psi(\vec{r})&amp;lt;/math&amp;gt; separatedely.

====Derivation of the Time-Independent and Space-Independent Schrödinger Equation====&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
Start from the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Take the derivative of both sides in respect to time:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\left(&lt;br /&gt;
\frac{\ddot{\phi}}{\phi}&lt;br /&gt;
-\frac{\dot{\phi}^2}{\phi^2}&lt;br /&gt;
\right) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
From now on, for the sake of simplicity, [//en.wikipedia.org/wiki/Notation_for_differentiation#Newton&#039;s_notation Newton&#039;s Notation] will be used to express derivatives. Simplifying the equation above yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\ddot{\phi}\phi = \dot{\phi}^2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Treat &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; as an independent variable and define &amp;lt;math&amp;gt;v(\phi) = \dot{\phi}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d}{dt}\left(\dot{\phi}\right)\phi = \left( \dot{\phi}\right)^2 \rightarrow&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{d}{dt}\left(v(\phi)\right)\phi = v^2(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By the chain rule:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt}\frac{dv}{d\phi}\phi = v^2(\phi) \rightarrow&lt;br /&gt;
\frac{dv}{d\phi}\phi = v(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writting in differential form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{dv}{v}=\frac{d\phi}{\phi}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Integrate both sides yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{dv}{v}=\int\frac{d\phi}{\phi}&lt;br /&gt;
        \rightarrow \ln{v} = \ln{\phi} + C_1&lt;br /&gt;

&lt;br /&gt;
The Schrödinger Equation is a [//en.wikipedia.org/wiki/Linear_differential_equation linear] [//en.wikipedia.org/wiki/Partial_differential_equation partial differential equation] that governs the [[Wave-Particle Duality | wave function]] of a [//en.wikipedia.org/wiki/Quantum_mechanics quantum mechanical system]&amp;lt;ref name=&amp;quot;Griffts Quantum&amp;quot;&amp;gt;Griffiths, David J. (2004). Introduction to Quantum Mechanics (2nd ed.). Prentice Hall. ISBN 978-0-13-111892-8.&amp;lt;/ref&amp;gt;. Similar to [[Newton&#039;s Second Law: the Momentum Principle | Newton&#039;s Laws]], the Schrödinger Equation is an equation of motion, meaning that it&#039;s capable of describing the time-evolution of a position analog of a system.&lt;br /&gt;
&lt;br /&gt;
The free particle is the name given to the system consisting of a single particle subject to a null or constant potential everywhere in space. It&#039;s the simplest system to which the Schrödinger Equation has a solution with physical meaning.&lt;br /&gt;
&lt;br /&gt;
Although the free-particle solution does not have ample practical use in the field of Physics, the methods and conclusions that come from the solution of this system are of great use in a plethora of other quantum systems.&lt;br /&gt;
&lt;br /&gt;
==The General Schrödinger Equation==&lt;br /&gt;
&lt;br /&gt;
The general formulation of the Schrödinger Equation for a time-dependent system of non-relativistic particles in [//en.wikipedia.org/wiki/Bra–ket_notation Bra-Ket notation] is:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;i \hbar \frac{d}{d t}\vert\Psi(t)\rangle = \hat H\vert\Psi(t)\rangle&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Here &amp;lt;math&amp;gt;i = \sqrt{-1}&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Imaginary_unit imaginary unit]. &amp;lt;math&amp;gt;\hbar&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Planck_constant reduced Planck&#039;s constant]. &amp;lt;math&amp;gt;\vert\Psi(t)\rangle&amp;lt;/math&amp;gt; is the state vector of the quantum system at time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;, and &amp;lt;math&amp;gt;\hat H&amp;lt;/math&amp;gt; is the [//en.wikipedia.org/wiki/Hamiltonian_(quantum_mechanics) Hamiltonian operator]. For a single particle, the general Schrödinger Equation reduces to a single linear partial differential equation:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r},t)\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\Psi(\vec{r},t)&amp;lt;/math&amp;gt; becomes the wave function of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;. &amp;lt;math&amp;gt;V(\vec{r},t)&amp;lt;/math&amp;gt; is the scalar potential energy of the particle at position &amp;lt;math&amp;gt;\vec{r}&amp;lt;/math&amp;gt; and time &amp;lt;math&amp;gt;t&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Time-independent Potential and Separation of Variables==&lt;br /&gt;
&lt;br /&gt;
The [[Potential Energy | potential energy]] of a system is often not an explicit function of time, that is &amp;lt;math&amp;gt;\frac{\partial V}{\partial t} = 0&amp;lt;/math&amp;gt;. Implying that, for such systems, the Schrödinger Equation of a single particle may be written as:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\frac{d}{d t}\Psi(\vec{r},t) = - \frac{\hbar^2}{2m} \nabla ^2 \Psi(\vec{r},t) + V(\vec{r})\Psi(\vec{r},t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
This, along with the [//en.wikipedia.org/wiki/Spectral_theorem spectral theorem] allows us to assume that the solution for this equation may be obtained through the separation of variables. That is, expressing the wave function as a product of a time-independent and a position-independent function:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\Psi(\vec{r},t) \equiv \psi(\vec{r})\phi(t) \rightarrow&lt;br /&gt;
i\hbar\frac{d}{d t}\psi(\vec{r})\phi(t) = - \frac{\hbar^2}{2m} \nabla ^2 \psi(\vec{r})\phi(t) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Expanding the derivatives through the [//en.wikipedia.org/wiki/Chain_rule chain rule] yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\psi(\vec{r})\frac{d}{d t}\phi(t) = - \frac{\hbar^2}{2m} \phi(t)\nabla ^2 \psi(\vec{r}) + V(\vec{r})\psi(\vec{r})\phi(t)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dividing both sides of the equation by &amp;lt;math&amp;gt;\psi(\vec{r})\phi(t)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The left side of this equation is position-independent, and the right side of the equation is time-independent. Therefore, we have successfully [https://en.wikipedia.org/wiki/Separation_of_variables#Partial_differential_equations separated variables], allowing us to solve for &amp;lt;math&amp;gt;\phi(t)&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;\psi(\vec{r})&amp;lt;/math&amp;gt; separatedely. Doing so yields:&lt;br /&gt;

====Time-Independent Schrödinger Equation for 1 Particle====&lt;br /&gt;
&amp;lt;math&amp;gt;- \frac {\hbar ^2}{2m} \nabla^2\psi(\vec{r}) + V(\vec{r})\psi(\vec{r})= E \psi(\vec{r})&amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours&amp;quot;&amp;gt;&lt;br /&gt;
====Space-Independent Schrödinger Equation for 1 Particle====&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{d}{d t}\phi(t)= -\frac{i}{\hbar}\left(E + V \right)\phi(t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A full derivation of this equations can be found below:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div class=&amp;quot;toccolours mw-collapsible mw-collapsed&amp;quot;&amp;gt;&lt;br /&gt;
====Derivation of the Time-Independent and Space-Independent Schrödinger Equation====&lt;br /&gt;
&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
Start from the Separated Equation for 1 Particle:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{i\hbar\frac{d}{d t}\phi(t)}{\phi(t)} = -\frac{\hbar^2}{2m} \frac{\nabla ^2 \psi(\vec{r})}{\psi(\vec{r})} + V(\vec{r})&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Take the derivative of both sides in respect to time:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
i\hbar\left(&lt;br /&gt;
\frac{\ddot{\phi}}{\phi}&lt;br /&gt;
-\frac{\dot{\phi}^2}{\phi^2}&lt;br /&gt;
\right) = 0&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
From now on, for the sake of simplicity, [//en.wikipedia.org/wiki/Notation_for_differentiation#Newton&#039;s_notation Newton&#039;s Notation] will be used to express derivatives. Simplifying the equation above yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\ddot{\phi}\phi = \dot{\phi}^2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Treat &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; as an independent variable and define &amp;lt;math&amp;gt;v(\phi) = \dot{\phi}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d}{dt}\left(\dot{\phi}\right)\phi = \left( \dot{\phi}\right)^2 \rightarrow&lt;br /&gt;
\rightarrow&lt;br /&gt;
\frac{d}{dt}\left(v(\phi)\right)\phi = v^2(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
By the chain rule:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt}\frac{dv}{d\phi}\phi = v^2(\phi) \rightarrow&lt;br /&gt;
\frac{dv}{d\phi}\phi = v(\phi)&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Re-writting in differential form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{dv}{v}=\frac{d\phi}{\phi}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Integrate both sides yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int\frac{dv}{v}=\int\frac{d\phi}{\phi}&lt;br /&gt;
        \rightarrow \ln{v} = \ln{\phi} + C_1&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solve for &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt; and simplify arbitrary constants:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
v(\phi)=C_1\phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Substitute in the definition of &amp;lt;math&amp;gt;v(\phi)&amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\frac{d\phi}{dt} = C_1 \phi&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Rewrite in differential form and integrate:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\int \frac{d\phi}{\phi} = \int C_1 dt&lt;br /&gt;
\rightarrow&lt;br /&gt;
\ln{\phi} = C_1 t + C_2&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Solving for &amp;lt;math&amp;gt;\phi&amp;lt;/math&amp;gt; and simplifying arbitrary constants yields:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;&lt;br /&gt;
\phi(t) = C_2 e^{C_1 t}&lt;br /&gt;
&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
::&lt;br /&gt;
&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;

&lt;br /&gt;
