Resonance-assisted tunneling in 4D normal-form Hamiltonians
Markus Firmbach, Felix Fritzsch, Roland Ketzmerick +1
Nonlinear resonances in the classical phase space lead to a significant enhancement of tunneling. We demonstrate that the double resonance gives rise to a complicated tunneling pea…

3D billiards: visualization of regular structures and trapping of chaotic trajectories
Markus Firmbach, Steffen Lange, Roland Ketzmerick +1
The dynamics in three-dimensional billiards leads, using a Poincaré section, to a four-dimensional map which is challenging to visualize. By means of the recently introduced 3D pha…
