Quantum Monte Carlo study of quasi-one-dimensional Bose gases
G. E. Astrakharchik, D. Blume, S. Giorgini +1
We study the behavior of quasi-one-dimensional (quasi-1d) Bose gases by Monte Carlo techniques, i.e., by the variational Monte Carlo, the diffusion Monte Carlo, and the fixed-node…
Quantum Monte Carlo study of the 3D-1D crossover for a trapped Bose gas
G. E. Astrakharchik, S. Giorgini
We investigate the cross-over from three to one dimension in a Bose gas confined in highly anisotropic traps. By using Quantum Monte-Carlo techniques, we solve the many-body Schrod…
Superfluidity vs Bose-Einstein condensation in a Bose gas with disorder
G. E. Astrakharchik, J. Boronat, J. Casulleras +1
We investigate the phenomenon of Bose-Einstein condensation and superfluidity in a Bose gas at zero temperature with disorder. By using the Diffusion Monte-Carlo method we calculat…
