Abstract
The microscopic origin of dissipation in collective motion of a quantu m many-body system is addressed in the framework of a parametric rando m matrix approach to the intrinsic dynamics. There are noticeable viol ations of the fluctuation-dissipation theorem and the energy diffusion has a markedly non-Gaussian character. Such features do not support t he usual Fokker-Planck approach to dissipation in large amplitude moti on of many fermion systems.
