On the relaxation of quantal time-dependent harmonic excitations

The approach to equilibrium of a quantal harmonic mode that exhibits time-dependent inertial or stiffness parameters, irreversibly coupled to a fermionic heat bath, is examined. It is assumed that the relaxation dynamics is described by a master equation derived in prior work, here endowed with a pa...
