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.
