Studying disorder and correlation effects on the phase diagram of bosons via mean field theory

Abstract

The thesis investigates the ground state phase diagram of interacting bosons using mean field theory on a Bose Hubbard model BHM A number of different relevant issues have been addressed here They include the effects of the periodic environment of the optical lattice on a Bose Einstein condensate The work nicely portrays the interplay of the condensate properties and symmetry of the underlying lattice vis a vis its coordination number A work on random disorder with a uniform distribution
