Perturbation-Free Prediction of Resonance-Assisted Tunneling in Mixed Regular--Chaotic Systems
Normann Mertig, Julius Kullig, Clemens Löbner +2
For generic Hamiltonian systems we derive predictions for dynamical tunneling from regular to chaotic phase-space regions. In contrast to previous approaches, we account for the re…
Integrable approximation of regular regions with a nonlinear resonance chain
Julius Kullig, Clemens Löbner, Normann Mertig +2
Generic Hamiltonian systems have a mixed phase space where regions of regular and chaotic motion coexist. We present a method for constructing an integrable approximation to such r…
Integrable Approximation of Regular Islands: The Iterative Canonical Transformation Method
Clemens Löbner, Steffen Löck, Arnd Bäcker +1
Generic Hamiltonian systems have a mixed phase space, where classically disjoint regions of regular and chaotic motion coexist. We present an iterative method to construct an integ…
