Phase-space localization of chaotic resonance states — •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 with escape a fundamental question concerns the phase-space localization of resonance states. For fully chaotic systems the resonance states are supported on a fractal set of classically trapped orbits. We investigate the possibility of quantum ergodicity, i.e. equidistribution of resonance states with respect to suitable classical densities on this fractal set. We observe remarkable deviations from naturally expected fractal densities on large scales and study their origin.
