Interaction picture as any other operator. In particular, let and be the density matrices in the interaction picture and the Schrödinger picture respectively. If there is probability to be in the physical state |"ψ"〉, then Transforming the Schrödinger equation into the interaction picture gives which states that in the interaction picture, a quantum state is evolved by the interaction part of the Hamiltonian as expressed in the interaction picture. If the operator "A" is time-independent (i.e., does not have "explicit time dependence"; see above), then the corresponding time evolution for "A"("t") is given by In the interaction picture the operators evolve in
Physics (American Physical Society magazine) Physics (American Physical Society magazine) Physics is an open access online publication containing commentaries on the best of the peer-reviewed research published in the journals of the American Physical Society. The editor-in-chief of "Physics" is Jessica Thomas. It highlights papers in "Physical Review Letters" and the "Physical Review" family of journals. The magazine was established in 2008. "Physics" contains three types of commentaries on research papers: journalistic articles ("Focus"), in depth pieces written by active researchers ("Viewpoints"), and short summaries of a research paper ("Synopsis") written by editorial staff. Readers get free access to the underlying research papers on which
