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
Australasian Physical & Engineering Sciences in Medicine Australasian Physical & Engineering Sciences in Medicine Australasian Physical & Engineering Sciences in Medicine is a quarterly peer-reviewed medical journal covering research on medical physics and biomedical engineering. It is the official journal of the Australasian College of Physical Scientists and Engineers in Medicine. The journal was first published in 1977 as "Australasian Physical Sciences in Medicine", obtaining its current name in 1980. It has been published by Springer Science+Business Media since 2010. The journal replaced the earlier "Australasian Bulletin of Medical Physics" and "Australasian Newsletter of Medical Physics", which was established in December 1959. The Kenneth Clarke Journal Prize
