Nonlinear behavior of bosons in anisotropic optical lattices
A. Cetoli, E. Lundh
We investigate the behavior of an array of Bose-Einstein condensate tubes described by means of a Bose-Hubbard Hamiltonian. Using an anisotropic non-polynomial Schrodinger equation…

Nearly-one-dimensional self-attractive Bose-Einstein condensates in optical lattices
L. Salasnich, A. Cetoli, B. A. Malomed +1
Within the framework of the mean-field description, we investigate atomic Bose-Einstein condensates (BECs), with attraction between atoms, under the action of strong transverse con…
