Formation of shock waves in a Bose-Einstein condensate
Bogdan Damski
We consider propagation of density wave packets in a Bose-Einstein condensate. We show that the shape of initially broad, laser-induced, density perturbation changes in the course…
Mean-field theory of Bose-Fermi mixtures in optical lattices
H. Fehrmann, M. A. Baranov, B. Damski +2
We determine the phase diagram of a mixture of ultracold bosons and polarized fermions placed in an optical lattice using mean field theory. In the limit of strong atom-atom intera…
Shock waves in ultracold Fermi (Tonks) gases
Bogdan Damski
It is shown that a broad density perturbation in a Fermi (Tonks) cloud takes a shock wave form in the course of time evolution. A very accurate analytical description of shock form…
Atomic Bose and Anderson glasses in optical lattices
B. Damski, J. Zakrzewski, L. Santos +2
An ultra cold atomic Bose gas in an optical lattice is shown to provide an ideal system for the controlled analysis of disordered Bose lattice gases. This goal may be easily achiev…
