Quantum Ergodicity in Open Chaotic Systems? — •Konstantin Clauß1, Martin Körber1, Arnd Bäcker1,2, and Roland Ketzmerick1,2 — 1TU Dresden, Institut für Theoretische Physik, Dresden — 2MPI für Physik komplexer Systeme, Dresden
In open quantum systems a fundamental question concerns the phase-space localization of resonance states. For a fully chaotic phase space the resonance states are supported on a fractal set of classically trapped orbits. We investigate the possibility of quantum ergodicity, i.e. semiclassical equidistribution with respect to suitable classical densities on this fractal set. We explain why these classical densities have to be chosen according to the quantum decay rate.
