A ˘ = i ℏ [ H ^ , A ^ ] + ∂ t A ^ ⟨ A ˘ ⟩ := d t A ^ {\displaystyle {\begin{aligned}&{\breve {A}}={\frac {i}{\hbar }}\left[{\hat {H}},{\hat {A}}\right]+{{\partial }_{t}}{\hat {A}}\\&\left\langle {\breve {A}}\right\rangle :={{d}_{t}}{\hat {A}}\end{aligned}}}
Sei ∂ t A ^ = 0 {\displaystyle {{\partial }_{t}}{\hat {A}}=0}
dann gilt im Heisenbergbild die Heisenbergesche Bewegungsgleichung
d t A ^ = A ˘ = i ℏ [ H ^ , A ^ ] {\displaystyle {{d}_{t}}{\hat {A}}={\breve {A}}={\frac {i}{\hbar }}\left[{\hat {H}},{\hat {A}}\right]}
