The role of the reservoir correlations in the relaxation rates for different coupling models

A quantal system is assumed to interact with a thermal environment. The fully coupled (FC) and the rotating wave approximation (RWA) models are considered to derive a generalized master equation for the reduced density operator in terms of the spectral density of the correlation function of the ther...
