Supersolid Order from Disorder: Hard-Core Bosons on the Triangular Lattice
Supersolid Order from Disorder: Hard-Core Bosons on the Triangular Lattice
We study the interplay of Mott localization, geometric frustration, and superfluidity for hard-core bosons with nearest-neighbor repulsion on the triangular lattice. For this model at half filling, we demonstrate that superfluidity survives for arbitrarily large repulsion, and that diagonal solid order emerges in the strongly correlated regime from an order-by-disorder …
