Extended Bose Hubbard model of interacting bosonic atoms in optical lattices: from superfluidity to density waves

G. Mazzarella, S. M. Giampaolo, F. Illuminati

For systems of interacting, ultracold spin-zero neutral bosonic atoms, harmonically trapped and subject to an optical lattice potential, we derive an Extended Bose Hubbard (EBH) mo…
