Reappearance of Localization in Open Chaotic Systems with a Partial Barrier — •Martin Körber1, Arnd Bäcker1,2, and Roland Ketzmerick1,21TU Dresden, Institut für Theoretische Physik, Dresden — 2MPI für Physik komplexer Systeme, Dresden

The chaotic dynamics of generic Hamiltonian systems is governed by partial barriers. They also strongly influence the system’s quantum-mechanical properties and lead to a localization of eigenstates on either side of a partial barrier. If the classical flux across a partial barrier is larger than the Planck cell, eigenstates delocalize in closed systems. In open systems, however, we observe that the resonance states localize again if the escape rate through the opening is sufficiently large. Here, we present a model which predicts the localization transition of a resonance state based on its decay rate.
