Interacting bosons in a triple well: Preface of many-body quantum chaos

K Wittmann W, ER Castro, A Foerster, LF Santos - Physical Review E, 2022 - APS
Systems of interacting bosons in triple-well potentials are of significant theoretical and
experimental interest. They are explored in contexts that range from quantum phase …

Statistics of phase space localization measures and quantum chaos in the kicked top model

Q Wang, M Robnik - Physical Review E, 2023 - APS
Quantum chaos plays a significant role in understanding several important questions of
recent theoretical and experimental studies. Here, by focusing on the localization properties …

Chaos in the three-site Bose-Hubbard model: Classical versus quantum

G Nakerst, M Haque - Physical Review E, 2023 - APS
We consider a quantum many-body system—the Bose-Hubbard system on three sites—
which has a classical limit, and which is neither strongly chaotic nor integrable but rather …

Phenomenology of quantum eigenstates in mixed-type systems: Lemon billiards with complex phase space structure

Č Lozej, D Lukman, M Robnik - Physical Review E, 2022 - APS
The boundary of the lemon billiards is defined by the intersection of two circles of equal unit
radius with the distance 2 B between their centers, as introduced by Heller and Tomsovic [EJ …

Many-body interference at the onset of chaos

E Brunner, L Pausch, EG Carnio, G Dufour… - Physical Review Letters, 2023 - APS
We unveil the signature of many-body interference across dynamical regimes of the Bose-
Hubbard model. Increasing the particles' indistinguishability enhances the temporal …

Robust nonergodicity of the ground states in the ensemble

AK Das, A Ghosh, IM Khaymovich - Physical Review B, 2024 - APS
In various chaotic quantum many-body systems, the ground states show nontrivial athermal
behavior despite the bulk states exhibiting thermalization. Such athermal states play a …

Optimal route to quantum chaos in the Bose–Hubbard model

L Pausch, A Buchleitner, EG Carnio… - Journal of Physics A …, 2022 - iopscience.iop.org
The dependence of the chaotic phase of the Bose–Hubbard Hamiltonian on particle number
N, system size L and particle density is investigated in terms of spectral and eigenstate …

Chaos and anomalous transport in a semiclassical Bose-Hubbard chain

D Marković, M Čubrović - Physical Review E, 2024 - APS
We study chaotic dynamics and anomalous transport in a Bose-Hubbard chain in the
semiclassical regime (the limit when the number of particles goes to infinity). We find that the …

Multifractality and excited-state quantum phase transition in ferromagnetic spin- Bose-Einstein condensates

ZX Niu, Q Wang - arXiv preprint arXiv:2407.20612, 2024 - arxiv.org
Multifractality of quantum states plays an important role for understanding numerous
complex phenomena observed in different branches of physics. The multifractal properties of …
