**Statistical Dynamics in Closed Quantum Sytems?** — •Christian Bartsch and Jochen Gemmer — Physics Department, University of Osnabrück, Barbarastr. 7, 49069 Osnabrück, Germany

The time evolution of closed finite quantum systems is strictly given by the Schrödinger equation which itself yields only completely reversible dynamics. Nevertheless, there are calculations by HAM (Hilbert Space Average Method) suggesting that under certain conditions statistical behaviour of appropriate variables can evolve in such systems. For certain classes of few particle systems the numerical solution of the time-dependent Schrödinger equation has been compared with those predictions. The occurrence of statistical dynamics has been analyzed especially with respect to the spatial structure of the potentials which the particles encounter.
