Phase diagram of quasi-two-dimensional bosons in laser speckle potential
G. E. Astrakharchik, K. V. Krutitsky, P. Navez
We have studied the phase diagram of a quasi-two-dimensional interacting Bose gas at zero temperature in the presence of random potential created by laser speckles. The superfluid…
Condensate fraction of cold gases in non-uniform external potential
G. E. Astrakharchik, K. V. Krutitsky
Exact calculation of the condensate fraction in multi-dimensional inhomogeneous interacting Bose systems which do not possess continuous symmetries is a difficult computational pro…
Dark solitons near the Mott-insulator--superfluid phase transition
K. V. Krutitsky, J. Larson, M. Lewenstein
Dark solitons of ultracold bosons in the vicinity of the Mott-insulator--superfluid phase transition are studied. Making use of the Gutzwiller ansatz we have found antisymmetric ei…
Local-field approach to the interaction of an ultracold dense Bose gas with a light field
K. V. Krutitsky, F. Burgbacher, J. Audretsch
The propagation of the electromagnetic field of a laser through a dense Bose gas is examined and nonlinear operator equations for the motion of the center of mass of the atoms are…
