Abstract Details: After a brief introduction of the ideas of experimental generation of synthetic gauge fields, I shall talk about the physics of interacting bosons in their presence. In particular, I shall discuss superfluid-Mott insulator (SI) transitions in a two dimensional square lattice at commensurate filling and in the presence of a synthetic periodic vector potential characterized by tunable strength p and period q. I shall then show the p and q dependence of the momentum distribution of the bosons in the Mott phases near the SI transitions and demonstrate that the bosons exhibit several reentrant field-induced SI transitions for any fixed period q. Finally I will comment on the superfluid density of the resultant superfluid state near such a SI transition.Click HERE for directions
