Entanglement in bipartite systems with symmetry: coupled chaotic kicked Bose-Hubbard systems
J. Himmelsbach, M. F. I. Kieler, A. Bäcker
We investigate the average eigenstate entanglement in a bipartite many-body system which exhibits a breaking of two local conservation laws into a global conserved quantity. Such a…
Eigenstate Correlations in Dual-Unitary Quantum Circuits: Partial Spectral Form Factor
Felix Fritzsch, Maximilian F. I. Kieler, Arnd Bäcker
While the notion of quantum chaos is tied to random matrix spectral correlations, also eigenstate properties in chaotic systems are often assumed to be described by random matrix t…
Deviations from random matrix entanglement statistics for kicked quantum chaotic spin- chains
Tabea Herrmann, Roland Brandau, Arnd Bäcker
It is commonly expected that for quantum chaotic many body systems, the statistical properties approach those of random matrices when increasing the system size. We demonstrate for…
Quantum transport through partial barriers in higher-dimensional systems
Jonas Stöber, Arnd Bäcker, Roland Ketzmerick
Partial transport barriers in the chaotic sea of Hamiltonian systems influence classical transport, as they allow for a small flux between chaotic phase-space regions only. We esta…
Classical Drift in the Arnold Web Induces Quantum Delocalization Transition
Jan Robert Schmidt, Arnd Bäcker, Roland Ketzmerick
We demonstrate that quantum dynamical localization in the Arnold web of higher-dimensional Hamiltonian systems is destroyed by an intrinsic classical drift. Thus quantum wave packe…
Characterizing quantum chaoticity of kicked spin chains
Tabea Herrmann, Maximilian F. I. Kieler, Arnd Bäcker
Quantum many-body systems are commonly considered as quantum chaotic if their spectral statistics, such as the level spacing distribution, agree with those of random matrix theory.…
