Heisenberg picture
英[ˈhaizənbə:ɡ ˈpiktʃə]美[ˈhaɪzənˌbɚɡ ˈpɪktʃɚ]
In physics, the Heisenberg picture (also called the Heisenberg representation) is a formulation (made by Werner Heisenberg while on Heligoland in the 1920s) of quantum mechanics in which the operators (observables and others) incorporate a dependency on time, but the state vectors are time-independent.
