Phase-space localization in absorbing quantum maps — •Konstantin Clauß1, Martin Körber1, Tobias Becker1, Arnd Bäcker1,2, and Roland Ketzmerick1,2 — 1TU Dresden, Institut für Theoretische Physik, Dresden — 2MPI für Physik komplexer Systeme, Dresden
In absorbing quantum systems a fundamental question concerns the phase-space localization of resonance states. The semi-classical description of a chaotic resonance state is given by a classical conditionally invariant measure with the same decay rate. We present a construction of such measures that generalizes the classical natural decay to arbitrary decay rates. We investigate (i) quantum mechanical deviations, (ii) the case of partial absorption, and (iii) the applicability to a mixed phase space.
