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…
