Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

Abstract The Yang–Baxter equation has long been recognised as the masterkey to
integrability, providing the basis for exactly solved models which capture the fundamental …

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 …

We study the spread complexity in two-mode Bose-Einstein condensates and unveil that the
long-time average of the spread complexity C¯ K can probe the dynamical transition from …

We investigate few-boson tunneling in a one-dimensional double well, covering the full
crossover from weak interactions to the fermionization limit of strong correlations. Based on …

Systems of interacting bosons in double-well potentials, modeled by two-site Bose-Hubbard
models, are of significant theoretical and experimental interest and attracted intensive …

We investigate the nonlinear self-trap** phenomenon of a Bose-Einstein condensate
(BEC) in a symmetric double well, emphasizing its underlying dynamical phase transition …

The N-body problem in a tilted double well requires new features for macroscopic quantum
superposition in ultracold atoms. In particular, one needs to go beyond the single-particle …

The precise control of quantum systems will play a major role in the realization of atomtronic
devices. As in the case of electronic systems, a desirable property is the ability to implement …

We obtain analytically close forms of benchmark quantum dynamics of the collapse and
revival (CR), the reduced density matrix, Von Neumann entropy, and fidelity for the XXZ …
