In physics, the Heisenberg picture or Heisenberg representation is a formulation (largely due to Werner Heisenberg in 1925) of quantum mechanics in which the operators (observables and others) incorporate a dependency on time, but the state vectors are time-independent, an arbitrary fixed basis rigidly … See more

According to See more1925Werner Heisenberg formulates the Heisenberg picture of quantum mechanics.1926Erwin Schrödinger formulates the Schrödinger picture of quantum mechanics.1931John von Neumann proves the Stone–von Neumann theorem, which shows that the Heisenberg and Schrödinger pictures are unitarily equivalent.1948Richard Feynman introduces the interaction picture, which is a hybrid of the Heisenberg and Schrödinger pictures.Commutator relations may look different than in the Schrödinger picture, because of the time dependence of operators. For example, consider the operators x(t1), x(t2), p(t1) and p(t2). The time evolution of those operators depends on the Hamiltonian of the … See more
