We show that also in this multi-band situation, the long-wavelength physics is described by a single-band Bose-Hubbard model. We determine the many-body renormalization of the tunneling and interaction parameters in the effective Bose-Hubbard Hamiltonian, and consider the resulting model at nonzero temperatures. We show that in particular for a one or two-dimensional optical lattice, the Mott insulator phase is more difficult to realize than anticipated previously.", "revisions": [ { "version": "v2", "updated": "2002-10-25T08:34:19.000Z" } ], "analyses": { "subjects": [ "39.25.+k", "67.40.-w", "03.75.Hh", "32.80.Pj" ], "keywords": [ "high filling factors", "optical lattice", "mott insulator transition", "atomic bose gas", "single-band bose-hubbard model" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
