Ultracold bosons with short-range interaction in regular optical lattices
TL;DR: In this article, a review of the recent developments in the field of ultracold atoms in optical lattices is presented, focusing mainly on the theory of different types of the bosonic systems in homogeneous lattices of different dimensions.

Journal ArticleDOI
Bose-Einstein-condensed gases in arbitrarily strong random potentials
TL;DR: In this article, Bose-Einstein-condensed gases in external spatially random potentials are considered in the frame of a stochastic self-consistent mean-field approach.
Journal ArticleDOI
Mean-field phase diagram of disordered bosons in a lattice at nonzero temperature
TL;DR: In this paper, a periodic lattice with on-site disorder at low but nonzero temperatures is considered within a mean-field theory and the criteria used for the definition of the superfluid, Mott insulator and Bose glass are analysed.
Journal ArticleDOI
One-dimensional Bose gas in optical lattices of arbitrary strength
TL;DR: In this paper, the Bose gas with contact interaction in optical lattices at zero temperature is investigated by means of the exact diffusion Monte Carlo algorithm, and the results obtained from the fundamental continuous model are compared with those obtained from lattice (discrete) Bose-Hubbard model, using exact diagonalization, and from the quantum sine-Gordon model.
