Cold atoms confined to optical lattices offer the unique opportunity for direct simulation of strongly correlated models in a pristine environment. Recent experimental progress in simulating the zero-range Bose-Hubbard model with bosonic atoms in an optical lattice provides a direct experimental probe of the superfluid to Mott phase transition. Another lattice model, the extended Bose-Hubbard model, yields a rich but contested phase diagram which includes the possibility of supersolid and density wave order. I will discuss a specific proposal designed to extend the range of interaction in these otherwise zero-range systems to effectively simulate an extended Bose-Hubbard model in a cold atom optical lattice. I will also discuss potential issues affecting experimental detection of supersolid and density wave order.
