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,…
Quantum coherence controls the nature of equilibration in coupled chaotic systems
Jethin J. Pulikkottil, Arul Lakshminarayan, Shashi C. L. Srivastava +3
A bipartite system whose subsystems are fully quantum chaotic and coupled by a perturbative interaction with a tunable strength is a paradigmatic model for investigating how isolat…
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…
Creating triple-NOON states with ultracold atoms via chaos-assisted tunneling
Guillaume Vanhaele, Arnd Bäcker, Roland Ketzmerick +1
Triple-NOON states are superpositions of the form involving bosonic quanta distributed over…
