Memory Effects in Quantum Theory of Relaxation

Abstract:

We present an approach to theory of relaxation processes with memory in which the time evolution of one-particle distribution functions is coupled with the evolution of many-particle correlations associated with energy balance. The basic idea is to treat the mean interaction energy as an independent state variable in addition to one-particle distribution functions. The method is illustrated by two examples: relaxation in a system with weak pairwise interaction and relaxation in a two-band laser-excited semiconductor.
