  • Bose-Hubbard model in a strong effective magnetic field: Emergence of a chiral Mott insulator ground state 
    Dhar, A; Maji, M; Mishra, T; Pai, R. V; Mukerjee, S; Paramekanti, A (American Physical Society, 2012-04)
    Motivated by experiments on Josephson junction arrays, and cold atoms in an optical lattice in a synthetic magnetic field, we study the “fully frustrated” Bose-Hubbard model with half a magnetic flux quantum per plaquette. ...
  • Chiral Mott insulator with staggered loop currents in the fully frustrated Bose-Hubbard model 
    Dhar, A; Mishra, T; Maji, M; Pai, R. V; Mukerjee, S; Paramekanti, A (American Physical Society, 2013-05-01)
    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 ...
  • Hard-Core Bosons in a Zig-Zag Optical Superlattice 
    Dhar, A; Mishra, T; Pai, R. V; Mukerjee, S; Das, B. P (American Physical Society, 2013-11-21)
    We study a system of hard-core bosons at half-filling in a one-dimensional optical superlattice. The bosons are allowed to hop to nearest- and next-nearest-neighbor sites. We obtain the ground-state phase diagram as a ...
