Quantenmechanik
Failed to parse (unknown function "\begin{align}"): {\displaystyle \begin{align} & \overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\frown}$}}{A}=\frac{i}{\hbar }\left[ \hat{H},\hat{A} \right]+{{\partial }_{t}}\hat{A} \\ & \left\langle {\overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\frown}$}}{A}} \right\rangle :={{d}_{t}}\hat{A} \end{align}}
dann gilt im Heisenbergbild die Heisenbergesche Bewegungsgleichung
Failed to parse (syntax error): {\displaystyle {{d}_{t}}\hat{A}=\overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\frown}$}}{A}=\frac{i}{\hbar }\left[ \hat{H},\hat{A} \right]}
