Normal and anomalous densities in Bose-Einstein condensate with optical lattices
M. Bendacha, Abdelaali Boudjemâa
We study the quantum phase transition from the superfluid to the Mott insulator state in two and three dimensional Bose-Einstein condensate (BEC) with optical lattices using Bose-H…

Theory of excitations of dipolar Bose-Einstein condensate at finite temperature
Abdelaali Boudjemaa
We present a systematic study of dilute three-dimensional dipolar Bose gas employing a finite temperature perturbation theory (beyond the mean field). We analyze in particular the…

Collective modes and generation of a new vortex in a trapped Bose gas at finite temperature
Abdelâali Boudjemâa
The dynamics of Bose-Einstein condensate (BEC) is studied at nonzero temperatures using our variational time-dependent-HFB formalism. We have shown that this approach is an efficie…
