Chiral bosonic phases on the Haldane honeycomb lattice

Recent experiments in ultracold atoms and photonic systems have realized lattice models with artificial gauge fields. Here the authors introduce a bosonic version of the Haldane Hubbard Hamiltonian on the honeycomb lattice and use several analytical and numerical methods to uncover a consistent picture of the phase diagram. Three distinct phases are found: chiral superfluid, uniform superfluid, and a plaquette Mott insulator, all of which should be accessible to future experiments.
