摘要：

The microscopic origin of dissipation in collective motion of a quantum many-body system is addressed in the framework of a parametric random matrix approach to the intrinsic dynamics. There are noticeable violations of the fluctuation-dissipation theorem and the energy diffusion has a markedly non-Gaussian character. Such features do not support the usual Fokker-Planck approach to dissipation in large amplitude motion of many fermion systems.
