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…
Semiclassical foundation of universality in chaotic quantum circuits
Maximilian F. I. Kieler, Felix Fritzsch, Arnd Bäcker
The fundamental correspondence between quantum chaotic single-particle systems and random matrix theory is well-understood via periodic orbit theory. In contrast, we show that many…
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…
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…
Universal spectral correlations in interacting chaotic few-body quantum systems
Felix Fritzsch, Maximilian F. I. Kieler
The emergence of random matrix spectral correlations in interacting quantum systems is a defining feature of quantum chaos. We study such correlations in terms of the spectral form…
