Berry curvature of interacting bosons in a honeycomb lattice

Berry curvature of interacting bosons in a honeycomb lattice

We consider soft-core bosons with on-site interaction loaded in the honeycomb lattice with different site energies for the two sublattices. Using both a mean-field approach and quantum Monte Carlo simulations, we show that the topology of the honeycomb lattice results in a nonvanishing Berry curvatu...
