Interacting fermions in quasi-one-dimensional harmonic traps
G. E. Astrakharchik, D. Blume, S. Giorgini +1
Quasi-one-dimensional (quasi-1d) two-component Fermi gases with effectively attractive and repulsive interactions are characterized for arbitrary interaction strength. The ground-s…
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…
Quasi-one-dimensional Bose gases with large scattering length
G. E. Astrakharchik, D. Blume, S. Giorgini +1
Bose gases confined in highly-elongated harmonic traps are investigated over a wide range of interaction strengths using quantum Monte Carlo techniques. We find that the properties…
Momentum distribution of a trapped Fermi gas with large scattering length
L. Viverit, S. Giorgini, L. P. Pitaevskii +1
Using a scattering length parametrization of the BCS-BEC crossover as well as the local density approximation for the density profile, we calculate the momentum distribution of a h…
