Supersolid Phase with Cold Polar Molecules on a Triangular Lattice
We study a system of heteronuclear molecules on a triangular lattice and analyze the potential of this system for the experimental realization of a supersolid phase. The ground state phase diagram contains superfluid, solid, and supersolid phases. At finite temperatures and strong interactions there is an additional emulsion region, in contrast with similar models with short-range interactions. We derive the maximal critical temperature T-c and the corresponding entropy S/N = 0.04(1) for supersolidity and find feasible experimental conditions for its realization.
