Query: The 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.
