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…

Influence of trapping potentials on the phase diagram of bosonic atoms in optical lattices
S. M. Giampaolo, F. Illuminati, G. Mazzarella +1
We study the effect of external trapping potentials on the phase diagram of bosonic atoms in optical lattices. We introduce a generalized Bose-Hubbard Hamiltonian that includes the…
