Consequences of Flooding in Open Quantum Systems — Arnd Bäcker, •Lars Bittrich, and Roland Ketzmerick — Institut für Theoretische Physik, Technische Universität Dresden, 01062 Germany

For closed systems with a mixed phase space, it was recently shown that quantum mechanically flooding of regular islands occurs when the Heisenberg time is larger than the tunneling time from the regular region to the chaotic sea [1]. In this case the regular eigenstates disappear. For open systems we investigate the phenomenon of flooding and the disappearance of regular states, where the escape time occurs as an additional time scale.
