Bose-Hubbard Model on a Honeycomb Superlattice: Quantum Phase Transitions and Lattice Effects
Wei-Wei Wang, Jin Yang, Jian-Ping Lv +1
We investigate the ground-state and finite-temperature phase diagrams of the Bose-Hubbard model on a honeycomb superlattice. The interplay between the superlattice potential depth…

Vacancy-assisted superfluid drag
Thomas G. Kiely, Chao Zhang, Erich J. Mueller
We study superfluid drag in the two-component Bose-Hubbard model with infinitely strong repulsive interactions. In this system, all transport is mediated by the motion of empty sit…

Thermocrystallization of lattice dipolar bosons coupled to a high-finesse cavity
Yaghmorassene Hebib, Chao Zhang, Massimo Boninsegni +1
Investigating finite temperature effects on quantum phases is key to their experimental realization. Finite temperature, and the interplay between quantum and thermal fluctuations…
