  • 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. (Physical Review A. 85(4); 2012; Article ID: 041602(R).)
    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. (Physical Review B. 87(17); 2013; Article no. 174501.)
    Motivated by experiments on Josephson junction arrays in a magnetic field and ultracold interacting atoms in an optical lattice in the presence of a "synthetic" orbital magnetic field, we study the "fully frustrated" ...
  • Hard-core bosons in a zig-zag optical superlattice 
    Dhar, A.; Mishra, T.; Pai, R.V.; Mukerjee, S.; Das, B.P. (Physical Review A. 88(5); 2013; Article No. 053625 .)
    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 ...
  • Quantum phases and phase transitions of frustrated hard-core bosons on a triangular ladder 
    Mishra, T.; Pai, R.V.; Mukerjee, S.; Paramekanti, A. (Physical Review B. 87(17); 2013; Article ID. 174504.)
    Kinetically frustrated bosons at half filling in the presence of a competing nearest-neighbor repulsion support a wide supersolid regime on the two-dimensional triangular lattice. We study this model on a two-leg ladder ...
  • Supersolid in a one-dimensional model of hard-core bosons 
    Mishra, T.; Pai, R.V.; Mukerjee, S. (Physical Review A. 89(1); 2014; Article No. 013615.)
    We study a system of hard-core boson on a one-dimensional lattice with frustrated next-nearest-neighbor hopping and nearest-neighbor interaction. At half filling, for equal magnitude of nearest- and next-nearest-neighbor ...
