Chiral Mott insulator with staggered loop currents in the fully frustrated Bose-Hubbard model
Chiral Mott insulator with staggered loop currents in the fully frustrated Bose-Hubbard model
Motivated by experiments on Josephson junction arrays in a magnetic field and ultracold interacting atoms in an optical lattice in the presence of synthetic orbital magnetic fields, we study the "fully frustrated" Bose-Hubbard model and quantum XY model with half a flux quantum per lattice plaquette. Using Monte Carlo simulations …
