Dynamical tunneling in a mixed phase spaceArnd Bäcker, Roland Ketzmerick, •Steffen Löck, and Lars Schilling — Institut für Theoretische Physik, Technische Universität Dresden, 01062 Dresden, Germany

The phase space of mixed systems consists of regular islands being dynamically separated from the chaotic sea. Quantum mechanically these phase space regions are connected by dynamical tunneling. We derive a formula predicting dynamical tunneling rates of regular states to the chaotic sea. Agreement with numerics for kicked systems with resonance-free islands will be presented. In addition this approach is applied to resonance assisted tunneling in systems with one dominating resonance chain.
