Query: Density Wave -Supersolid and Mott Insulator-Superfluid transition in
  presence of an artificial gauge field : a strong coupling perturbation
  approach   We study the effect of an artificial gauge field on the zero temperature
phase diagram of extended Bose Hubbard model, that describes ultra cold atoms
in optical lattices with long range interaction using strong coupling
perturbation theory . We determine analytically the effect of the artificial
gauge field on the density wave - supersolid (DW-SS) and the the Mott
insulator-superfluid (MI -SF) transition boundary . The momentum distribution
at these two transition boundaries is also calculated in this approach. It is
shown that such momentum distribution which can be observed in time of flight
measurement, reveals the symmetry of the gauge potential through the formation
of magnetic Brillouin zone and clearly distinguishes between the DW-SS and
MI-SF boundary. We also point out that in symmetric gauge the momentum
distribution structure at these transition boundaries bears distinctive
signatures of vortices in supersolid and superfluid phases.
