Abstract

The dynamics of an ultracold dilute gas of bosonic atoms in an optical\nlattice can be described by a Bose-Hubbard model where the system parameters\nare controlled by laser light. We study the continuous (zero temperature)\nquantum phase transition from the superfluid to the Mott insulator phase\ninduced by varying the depth of the optical potential, where the Mott insulator\nphase corresponds to a commensurate filling of the lattice (``optical\ncrystal''). Examples for formation of Mott structures in optical lattices with\na superimposed harmonic trap, and in optical superlattices are presented.\n
