Abstract
We consider two Hamiltonians that are close to each other, , and analyze the time decay of the corresponding that expresses the effect of an imperfect time reversal on the initial state . Our model Hamiltonians are deformed Wigner matrices that do not share a common eigenbasis. The main tools are new two-resolvent laws for such and .
