A striped supersolid phase in bosons on the triangular lattice

Using large-scale quantum Monte Carlo simulations, we explore the ground-state phase diagram of bosons hopping on a triangular lattice with nearest (V) and next-nearest (V') neighbor repulsive interactions. In the limit where V=0 but V' is large, we find an example of an unusual striped supersolid state that is stable at 1/2-filling. We discuss the peculiar properties of this phase, as well as the phase transitions out of it into the neighboring superfluid and Mott phases.
