Dynamic structure factor of ultracold Bose and Fermi gases in optical lattices
R. Roth, K. Burnett
We investigate the dynamic structure factor of atomic Bose and Fermi gases in one-dimensional optical lattices at zero temperature. The focus is on the generic behaviour of S(k,ome…
Phase Diagram of Bosonic Atoms in Two-Color Superlattices
R. Roth, K. Burnett
We investigate the zero temperature phase diagram of a gas of bosonic atoms in one- and two-color standing-wave lattices in the framework of the Bose-Hubbard model. We first introd…
Ultracold Bosonic Atoms in Disordered Optical Superlattices
R. Roth, K. Burnett
The influence of disorder on ultracold atomic Bose gases in quasiperiodic optical lattices is discussed in the framework of the one-dimensional Bose-Hubbard model. It is shown that…
Theory of Bose-Einstein condensation for trapped atoms
N. P. Proukakis, K. Burnett
We outline the general features of the conventional mean-field theory for the description of Bose-Einstein condensates at near zero temperatures. This approach, based on a phenomen…
