Quantum bright solitons in the Bose-Hubbard model with site-dependent repulsive interactions
L. Barbiero, B. A. Malomed, L. Salasnich
We introduce a one-dimensional (1D) spatially inhomogeneous Bose-Hubbard model (BHM) with the strength of the onsite repulsive interactions growing, with the discrete coordinate $z…

Magnetic phase transition in coherently coupled Bose gases in optical lattices
L. Barbiero, M. Abad, A. Recati
We describe the ground state of a gas of bosonic atoms with two coherently coupled internal levels in a deep optical lattice in a one dimensional geometry. In the single-band appro…

Quantum bright solitons in a quasi-one-dimensional optical lattice
Luca Barbiero, Luca Salasnich
We study a quasi-one-dimensional attractive Bose gas confined in an optical lattice with a superimposed harmonic potential by analyzing the effective one-dimensional Bose-Hubbard H…
