Bewegungsgleichung

Quantenmechanik

Failed to parse (unknown function "\begin{align}"): {\displaystyle \begin{align} & \breve{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}}\left\langle {\hat{A}} \right\rangle \end{align}}

Sei ${\partial }_t\hat{A}=0$

dann gilt im Heisenbergbild die Heisenbergesche Bewegungsgleichung

$d_t\hat{A}=\breve{A}=\frac{i}{\hslash }[\hat{H},\hat{A}]$
