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…
