Chaotic resonance modes in dielectric cavities: Product of conditionally invariant measure and universal fluctuations
Roland Ketzmerick, Konstantin Clauß, Felix Fritzsch +1
We conjecture that chaotic resonance modes in scattering systems are a product of a conditionally invariant measure from classical dynamics and universal exponentially distributed…
Boundary Chaos
Felix Fritzsch, Tomaž Prosen
Scrambling in many-body quantum systems causes initially local observables to spread uniformly over the whole available Hilbert space under unitary dynamics, which in lattice syste…
Eigenstate thermalization in dual-unitary quantum circuits: Asymptotics of spectral functions
Felix Fritzsch, Tomaž Prosen
The eigenstate thermalization hypothesis provides to date the most successful description of thermalization in isolated quantum systems by conjecturing statistical properties of ma…
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…
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…
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…
