Universal intensity statistics of multifractal resonance states
Konstantin Clauß, Felix Kunzmann, Arnd Bäcker +1
We conjecture that in chaotic quantum systems with escape the intensity statistics for resonance states universally follows an exponential distribution. This requires a scaling by…

Geometry of complex instability and escape in four-dimensional symplectic maps
Jonas Stöber, Arnd Bäcker
In four-dimensional symplectic maps complex instability of periodic orbits is possible, which cannot occur in the two-dimensional case. We investigate the transition from stable to…

Linear and logarithmic entanglement production in an interacting chaotic system
Sanku Paul, Arnd Bäcker
We investigate entanglement growth for a pair of coupled kicked rotors. For weak coupling, the growth of the entanglement entropy is found to be initially linear followed by a loga…
