Power-law trapping in the volume-preserving Arnold-Beltrami-Childress map
Swetamber Das, Arnd Bäcker
Understanding stickiness and power-law behavior of Poincaré recurrence statistics is an open problem for higher-dimensional systems, in contrast to the well-understood case of syst…
Entanglement in coupled kicked tops with chaotic dynamics
Tabea Herrmann, Maximilian F. I. Kieler, Felix Fritzsch +1
The entanglement of eigenstates in two coupled, classically chaotic kicked tops is studied in dependence of their interaction strength. The transition from the non-interacting and…
Structure of resonance eigenfunctions for chaotic systems with partial escape
Konstantin Clauß, Eduardo G. Altmann, Arnd Bäcker +1
Physical systems are often neither completely closed nor completely open, but instead they are best described by dynamical systems with partial escape or absorption. In this paper…
Resonance--Assisted Tunneling in Deformed Optical Microdisks with a Mixed Phase Space
Felix Fritzsch, Roland Ketzmerick, Arnd Bäcker
The life times of optical modes in whispering-gallery cavities crucially depend on the underlying classical ray dynamics and may be spoiled by the presence of classical nonlinear r…
Multifractal dimensions for random matrices, chaotic quantum maps, and many-body systems
Arnd Bäcker, Masudul Haque, Ivan M. Khaymovich
Multifractal dimensions allow for characterizing the localization properties of states in complex quantum systems. For ergodic states the finite-size versions of fractal dimensions…
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…
