Quantum phases of the extended bose-hubbard hamiltonian: Possibility of a supersolid state of cold atoms in optical lattices [link]Website  doi  abstract   bibtex   
Cold atom optical lattices typically simulate zero-range Hubbard models. We discuss the theoretical possibility of using excited states of optical lattices to generate extended range Hubbard models. We find that bosons confined to higher bands of optical lattices allow for a rich phase diagram, including the supersolid phase. Using Gutzwiller, mean-field theory we establish the parameter regime necessary to maintain metastable states generated by an extended Bose-Hubbard model.
