Resonance-assisted tunneling in deformed optical microdisk cavities — •Julius Kullig and Jan Wiersig — ITP, Otto-von-Guericke-Universität Magdeburg, 39106 Magdeburg, Germany

In generic systems tunneling not only occurs at energy barriers but also between classically disjoint regions in phase space. Nonlinear resonance chains which arise generically from system perturbations drastically enhance the tunneling effect which is then called resonance-assisted tunneling (RAT). While RAT is well studied for kicked Hamiltonian systems and experimentally observed in microwave billiards its application to optical cavities is less investigated. But here a recent experiment by [Kwak et al., Sci. Rep. 2015] suggests a particular relevance. In our talk we use perturbative methods for RAT to predict quality factors and optical mode structures of deformed microdisk cavities.
