Towards a Statistical Theory of Finite Systems and Compound States: Random Two-Body Interaction Approach
arXiv:cond-mat/9607035 · doi:10.1103/PhysRevE.54.2136
Abstract
The model of Fermi particles with random two-body interaction is investigated. This model allows to study the origin and accuracy of statistical laws in few-body systems, the role of interaction and chaos in thermalization, Fermi-Dirac distribution for quasi-particles with spreading widths, matrix elements of external field and enhancement of weak perturbation in chaotic compound states.
