Influence of sublattice bias on superfluid to Mott insulator transitions

We model the superfluid to Mott insulator transition for a Bose gas on a lattice with two inequivalent sublattices. Using the Gutzwiller ansatz, we produce phase diagrams and provide an understanding of the interplay between superfluidity on each sublattice. We explore how the Mott lobes split and describe the experimental signatures.

This study models the transition from superfluid to Mott insulator for a Bose gas on a lattice with two inequivalent sublattices, utilizing the Gutzwiller ansatz to produce phase diagrams and understand the interplay of superfluidity on each sublattice. The splitting of Mott lobes and experimental signatures are explored and described.
