Partial barriers to chaotic transport in 4D symplectic maps
Markus Firmbach, Arnd Bäcker, Roland Ketzmerick
Chaotic transport in Hamiltonian systems is often restricted due to the presence of partial barriers, leading to a limited flux between different regions in phase phase. Typically,…
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…
