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…
Correlation functions and momentum distribution of one-dimensional Bose systems
G. E. Astrakharchik, S. Giorgini
The ground-state correlation properties of a one-dimensional Bose system described by the Lieb-Liniger Hamiltonian are investigated by using exact quantum Monte Carlo techniques. T…
Critical temperature of Bose-Einstein condensation in trapped atomic Bose-Fermi mixtures
Alexander P. Albus, Stefano Giorgini, Fabrizio Illuminati +1
We calculate the shift in the critical temperature of Bose-Einstein condensation for a dilute Bose-Fermi mixture confined by a harmonic potential to lowest order in both the Bose-B…
