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 …

Quantum chaotic interacting N-particle systems are assumed to show fast and irreversible
spreading of quantum information on short (Ehrenfest) time scales∼ log N. Here, we show …

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 …

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 present an analytical description of the tunneling dynamics between two coupled Bose-
Einstein condensates in the Josephson regime. The model relies on the classical analogy …

We investigate the polaronic properties of a single impurity immersed in a weakly interacting
bosonic environment confined within a one-dimensional double-well potential using an …

We associate a bosonic network to each complete bipartite graph. A Hamiltonian is defined
with hopping terms on the edges of the graph, and a global interaction term depending on …

We present the quantum and classical study of a four-well trapped Bose–Einstein
condensate (BEC) modeled by the Bose–Hubbard Hamiltonian. The model used is …

We consider the fate of 1/N expansions in unstable many-body quantum systems, as
realized by a quench across criticality, and show the emergence of e 2 λ t/N as a …
