Towards a Statistical Theory of Finite Systems and Compound States: Random Two-Body Interaction Approach

摘要

The model of Fermi particles with random two-body interaction isinvestigated. This model allows to study the origin and accuracy of statisticallaws in few-body systems, the role of interaction and chaos in thermalization,Fermi-Dirac distribution for quasi-particles with spreading widths, matrixelements of external field and enhancement of weak perturbation in chaoticcompound states.
