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…
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.…
Fast Bit-Flipping based on a Stability Transition of Coupled Spins
Maximilian F. I. Kieler, Arnd Bäcker
A bipartite spin system is proposed for which a fast transfer from one defined state into another exists. For sufficient coupling between the spins, this implements a bit-flipping…
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…
