		<summary type="html">&lt;p&gt;Die Seite wurde neu angelegt: „{{Scripthinweis|Quantenmechanik|1|4}} Schrödingergleichung für Teilchen in Potenzialen V und A ( beide reell):  &amp;lt;math&amp;gt;\begin{align}  &amp;amp; i\hbar \dot{\Psi }(\bar{r…“&lt;/p&gt;
&lt;p&gt;&lt;b&gt;Neue Seite&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{Scripthinweis|Quantenmechanik|1|4}}&lt;br /&gt;
Schrödingergleichung für Teilchen in Potenzialen V und A ( beide reell):&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; i\hbar \dot{\Psi }(\bar{r},t)=\hat{H}\Psi =\frac{1}{2m}{{\left( \frac{\hbar }{i}\nabla -e\bar{A} \right)}^{2}}\Psi (\bar{r},t)+V\Psi (\bar{r},t) \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; V=e\Phi  \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; i\hbar \dot{\Psi }(\bar{r},t)=\frac{1}{2m}\left( \frac{\hbar }{i}\nabla -e\bar{A} \right)\left( \frac{\hbar }{i}\nabla -e\bar{A} \right)\Psi (\bar{r},t)+V\Psi (\bar{r},t) \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; =\frac{1}{2m}\left[ -{{\hbar }^{2}}\Delta \Psi +i\hbar e\nabla \left( \bar{A}\Psi  \right)+i\hbar e\bar{A}\left( \nabla \Psi  \right)+{{e}^{2}}{{A}^{2}}\Psi  \right]+V\Psi (\bar{r},t) \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dabei sind alle Terme außer dem ersten und dem letzten (V) magnetfeldabhängig, also abhängig von&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\bar{A}(\bar{r},t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Die Gleichung kann komplex konjugiert werden:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;i\hbar \dot{\Psi }*(\bar{r},t)=\frac{1}{2m}\left[ -{{\hbar }^{2}}\Delta \Psi *-i\hbar e\nabla \left( \bar{A}\Psi * \right)-i\hbar e\bar{A}\left( \nabla \Psi * \right)+{{e}^{2}}{{A}^{2}}\Psi * \right]+V\Psi *(\bar{r},t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Damit ergibt sich eine Bewegungsgleichung für die Wahrscheinlichkeitsdichte:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; i\hbar \frac{\partial }{\partial t}{{\left| \Psi (\bar{r},t) \right|}^{2}}=i\hbar \frac{\partial }{\partial t}\left( \Psi (\bar{r},t)\Psi *(\bar{r},t) \right)=\Psi *(\bar{r},t)i\hbar \frac{\partial }{\partial t}\Psi (\bar{r},t)+\Psi (\bar{r},t)i\hbar \frac{\partial }{\partial t}\Psi *(\bar{r},t) \\&lt;br /&gt;
&amp;amp; i\hbar \frac{\partial }{\partial t}{{\left| \Psi (\bar{r},t) \right|}^{2}}=i\hbar \left( \Psi *(\bar{r},t)\dot{\Psi }(\bar{r},t)+\dot{\Psi }*(\bar{r},t)\Psi (\bar{r},t) \right)=\Psi *\hat{H}\Psi -\Psi (\hat{H}\Psi )* \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; i\hbar \frac{\partial }{\partial t}{{\left| \Psi (\bar{r},t) \right|}^{2}}=\frac{-{{\hbar }^{2}}}{2m}\left( \Psi *\Delta \Psi -\Psi \Delta \Psi * \right)+\frac{{{e}^{2}}}{2m}\left[ \Psi *{{{\bar{A}}}^{2}}\Psi -\Psi {{{\bar{A}}}^{2}}\Psi * \right]+\Psi *V\Psi -\Psi V\Psi * \\&lt;br /&gt;
&amp;amp; \quad \quad \quad \quad \quad \quad +\frac{i\hbar e}{2m}\left( \Psi *\nabla \left( \bar{A}\Psi  \right)+\bar{A}\Psi \nabla \Psi *+\Psi \nabla \left( \bar{A}\Psi * \right)+\bar{A}\Psi *\nabla \Psi  \right) \\&lt;br /&gt;
&amp;amp; \Psi *{{{\bar{A}}}^{2}}\Psi -\Psi {{{\bar{A}}}^{2}}\Psi *=0 \\&lt;br /&gt;
&amp;amp; \Psi *V\Psi -\Psi V\Psi *=0 \\&lt;br /&gt;
&amp;amp; \Psi *\nabla \left( \bar{A}\Psi  \right)+\bar{A}\Psi \nabla \Psi *=\Psi \nabla \left( \bar{A}\Psi * \right)+\bar{A}\Psi *\nabla \Psi =\nabla \left( \Psi \bar{A}\Psi * \right) \\&lt;br /&gt;
&amp;amp; \Rightarrow i\hbar \frac{\partial }{\partial t}{{\left| \Psi (\bar{r},t) \right|}^{2}}=\frac{-{{\hbar }^{2}}}{2m}\left( \Psi *\Delta \Psi -\Psi \Delta \Psi * \right)+\frac{i\hbar e}{m}\nabla \left( \Psi \bar{A}\Psi * \right) \\&lt;br /&gt;
&amp;amp; \Psi *\Delta \Psi -\Psi \Delta \Psi *=\nabla \left( \Psi *\nabla \Psi -\Psi \nabla \Psi * \right)-\left( \nabla \Psi *\nabla \Psi -\nabla \Psi \nabla \Psi * \right) \\&lt;br /&gt;
&amp;amp; \left( \nabla \Psi *\nabla \Psi -\nabla \Psi \nabla \Psi * \right)=0 \\&lt;br /&gt;
&amp;amp; \Rightarrow i\hbar \frac{\partial }{\partial t}{{\left| \Psi (\bar{r},t) \right|}^{2}}=\frac{-{{\hbar }^{2}}}{2m}\nabla \left( \Psi *\nabla \Psi -\Psi \nabla \Psi * \right)+\frac{i\hbar e}{m}\nabla \left( \Psi \bar{A}\Psi * \right) \\&lt;br /&gt;
&amp;amp; \Rightarrow i\hbar \frac{\partial }{\partial t}{{\left| \Psi (\bar{r},t) \right|}^{2}}=\nabla \left[ \frac{-{{\hbar }^{2}}}{2m}\left( \Psi *\nabla \Psi -\Psi \nabla \Psi * \right)+\frac{i\hbar e}{m}\left( \Psi \bar{A}\Psi * \right) \right] \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
Diese Gleichung hat die Form einer Kontinuitätsgleichung der lokalen Wahrscheinlichkeitserhaltung für die Wahrscheinlichkeitsdichte quantenmechanischer Wellenfunktionen im elektromagnetischen Feld&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{\partial }{\partial t}{{\left| \Psi (\bar{r},t) \right|}^{2}}+\nabla \cdot \bar{j}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
Die Wahrscheinlichkeitsstromdichte lautet:&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; \bar{j}=\frac{\hbar }{2mi}\left( \Psi *\nabla \Psi -\Psi \nabla \Psi * \right)-\frac{e}{m}\left( \Psi \bar{A}\Psi * \right) \\&lt;br /&gt;
&amp;amp; =\frac{1}{2m}\left\{ \Psi *\left( \frac{\hbar }{i}\nabla -e\bar{A} \right)\Psi +\Psi \left( -\frac{\hbar }{i}\nabla -e\bar{A} \right)\Psi * \right\} \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
Denn:&lt;br /&gt;
Wenn die Kontinuitätsgleichung &amp;lt;math&amp;gt;\frac{\partial }{\partial t}{{\left| \Psi (\bar{r},t) \right|}^{2}}+\nabla \cdot \bar{j}=0&amp;lt;/math&amp;gt;erfüllt sein soll, so muss der Wahrscheinlichkeitsstrom die obige Form haben !&lt;br /&gt;
Die Kontinuitätsgleichung erhält man sauber durch Anwenden der Schrödingergleichung auf Die Wahrscheinlichkeit !&lt;br /&gt;
Dabei bezeichnet man&lt;br /&gt;
&amp;lt;math&amp;gt;\bar{j}=\frac{\hbar }{2mi}\left( \Psi *\nabla \Psi -\Psi \nabla \Psi * \right)&amp;lt;/math&amp;gt; als die freie Wahrscheinlichkeitsstromdichte, die im elektromagnetischen Potenzial durch den Potenzialterm &amp;lt;math&amp;gt;-\frac{e}{m}\left( \Psi \bar{A}\Psi * \right)&amp;lt;/math&amp;gt; ergänzt wird&lt;br /&gt;
&amp;lt;math&amp;gt;\bar{j}=\frac{1}{2m}\left\{ \Psi *{{{\hat{\bar{P}}}}_{kin}}\Psi +\Psi \left( {{{\hat{\bar{P}}}}_{kin}}\Psi  \right)* \right\}&amp;lt;/math&amp;gt;&lt;br /&gt;
Mit dem kinetischen Impulsoperator&lt;br /&gt;
&amp;lt;math&amp;gt;{{\hat{\bar{P}}}_{kin}}:=\frac{\hbar }{i}\nabla -e\bar{A}&amp;lt;/math&amp;gt;&lt;br /&gt;
Führt man den kinetischen Impuls ein, so ist die Form analog zur Darstellung der freien Wahrscheinlichkeitsstromdichte verallgemeinert !&lt;br /&gt;
&amp;lt;u&amp;gt;&amp;#039;&amp;#039;&amp;#039;Bemerkungen&amp;#039;&amp;#039;&amp;#039;&amp;lt;/u&amp;gt;&lt;br /&gt;
# Neben dem kanonischen Impulsoperator: &amp;lt;math&amp;gt;{{\hat{\bar{P}}}_{{}}}:=\frac{\hbar }{i}\nabla &amp;lt;/math&amp;gt;, wobei klassisch &amp;lt;math&amp;gt;{{p}_{i}}=\frac{\partial L}{\partial {{{\dot{q}}}_{i}}}&amp;lt;/math&amp;gt; haben wir es nun mit dem kinetischen Impulsoperator &amp;lt;math&amp;gt;{{\hat{\bar{P}}}_{kin}}:=\frac{\hbar }{i}\nabla -e\bar{A}&amp;lt;/math&amp;gt;zu tun. Dieser hängt mit dem Geschwindigkeitsoperator  &amp;lt;math&amp;gt;\hat{\bar{v}}:=\frac{{{{\hat{\bar{P}}}}_{kin}}}{m}&amp;lt;/math&amp;gt;zusammen, wobei der &amp;#039;&amp;#039;&amp;#039;Geschwindigkeitsoperator &amp;#039;&amp;#039;&amp;#039;&amp;lt;math&amp;gt;\hat{\bar{v}}:=\frac{{{{\hat{\bar{P}}}}_{kin}}}{m}&amp;lt;/math&amp;gt;&amp;#039;&amp;#039;&amp;#039;NICHT &amp;#039;&amp;#039;&amp;#039;die Zeitableitung des Orts- Operators repräsentiert.&lt;br /&gt;
Also: &amp;lt;math&amp;gt;{{\hat{\bar{P}}}_{kin}}=m\hat{\bar{v}}&amp;lt;/math&amp;gt;und &amp;lt;math&amp;gt;\hat{p}\ne m\hat{\bar{v}}&amp;lt;/math&amp;gt;&lt;br /&gt;
# Mit Hilfe des Geschwindigkeitsoperators lautet die Kontinuitätsgleichung&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{\partial }{\partial t}{{\left| \Psi (\bar{r},t) \right|}^{2}}+\nabla \cdot \bar{j}=0&amp;lt;/math&amp;gt;mit &amp;lt;math&amp;gt;\bar{j}=\frac{1}{2}\left\{ \Psi *\hat{\bar{v}}\Psi +\Psi \left( \hat{\bar{v}}\Psi  \right)* \right\}&amp;lt;/math&amp;gt;&lt;br /&gt;
Dies ist ganz analog zur Kontinuitätsgleichung für klassische Dichten:&lt;br /&gt;
&amp;lt;math&amp;gt;\dot{\rho }+\nabla \cdot \bar{j}=0&amp;lt;/math&amp;gt;mit &amp;lt;math&amp;gt;\bar{j}=\rho \cdot \bar{v}&amp;lt;/math&amp;gt;&lt;br /&gt;
Quantenmechanisch muss man lediglich die symmetrische reelle Form &amp;lt;math&amp;gt;\bar{j}=\operatorname{Re}\left\{ \Psi *\hat{\bar{v}}\Psi  \right\}&amp;lt;/math&amp;gt;wählen, da hier &amp;lt;math&amp;gt;\rho \cdot \hat{\bar{v}}&amp;lt;/math&amp;gt;oder &amp;lt;math&amp;gt;\hat{\bar{v}}\rho &amp;lt;/math&amp;gt;nicht wohldefiniert ist. ( Worauf wirkt der Operator ?)&lt;br /&gt;
# In &amp;lt;math&amp;gt;\hat{H}=\frac{1}{2m}{{\left( \hat{\bar{p}}-e\bar{A}(\hat{\bar{r}},t) \right)}^{2}}=\frac{1}{2m}\left( {{{\hat{\bar{p}}}}^{2}}-e\hat{\bar{p}}\bar{A}-e\bar{A}\hat{\bar{p}}+{{e}^{2}}{{A}^{2}} \right)&amp;lt;/math&amp;gt; ist die Reihenfolge der Faktoren zu beachten !&lt;br /&gt;
Nur in der Coulomb- Eichung &amp;lt;math&amp;gt;\nabla \cdot \bar{A}=0&amp;lt;/math&amp;gt;gilt:&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&amp;amp; \left( \hat{\bar{p}}\bar{A}+\bar{A}\hat{\bar{p}} \right)\Psi =\frac{\hbar }{i}\left[ \nabla \left( \bar{A}\Psi  \right)+\bar{A}\left( \nabla \Psi  \right) \right]=\frac{\hbar }{i}\left[ \left( \nabla \cdot \bar{A} \right)\Psi +2\bar{A}\left( \nabla \Psi  \right) \right] \\&lt;br /&gt;
&amp;amp; \nabla \cdot \bar{A}=0 \\&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
Im Spezialfall der Coulomb- Eichung. Somit:&lt;br /&gt;
&amp;lt;math&amp;gt;\left( \hat{\bar{p}}\bar{A}+\bar{A}\hat{\bar{p}} \right)\Psi =2\bar{A}\hat{\bar{p}}\Psi &amp;lt;/math&amp;gt;&lt;br /&gt;
Also in diesem Fall:&lt;br /&gt;
&amp;lt;math&amp;gt;\hat{H}=\frac{1}{2m}{{\left( \hat{\bar{p}}-e\bar{A}(\hat{\bar{r}},t) \right)}^{2}}=\frac{1}{2m}\left( {{{\hat{\bar{p}}}}^{2}}-2e\bar{A}\hat{\bar{p}}+{{e}^{2}}{{A}^{2}} \right)&amp;lt;/math&amp;gt;&lt;br /&gt;
Merke: Die Coulombeichung bringt &amp;lt;math&amp;gt;\bar{A}&amp;lt;/math&amp;gt;und &amp;lt;math&amp;gt;\hat{p}&amp;lt;/math&amp;gt;zum Vertauschen !&lt;br /&gt;
# Im Gaußschen Maßsystem gilt:&lt;br /&gt;
&amp;lt;math&amp;gt;\hat{H}=\frac{1}{2m}{{\left( \hat{\bar{p}}-\frac{e}{c}\bar{A} \right)}^{2}}&amp;lt;/math&amp;gt;&lt;/div&gt;</summary>
