    Percolation-enhanced supersolids in the extended Bose-Hubbard model
    Kemburi, B. M.; Scarola, Vito W. (American Physical Society, 2012-01-04)
    We theoretically study the stability of lattice supersolid states in the extended Bose-Hubbard model with bounded spatial disorder. We construct a disorder mean-field theory and compare with quantum Monte Carlo calculations. The supersolid survives weak disorder on the simple cubic lattice. We also find that increasing disorder strength can transform a lattice solid into a supersolid as it tends to percolate through the disorder landscape.
