We study the time evolution of two coupled many-body quantum systems, one of which is
assumed to be Bose condensed. Specifically, we consider two ultracold atomic clouds each …

We study the interplay of chaos and tunneling between two weakly coupled Bose-
Josephson junctions. The classical phase space of the composite system has a mixed …

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 …

The entanglement between two weakly coupled bosonic Josephson junctions is studied in
relation to the classical mixed phasespace structure of the system, containing symmetry …

Considering a two-dimensional (2D) Bose-Hubbard spinor lattice with weak nearest-
neighbor interactions and no particle transfer between sites, we theoretically study the …
