Released momentum distribution of a Fermi gas in the BCS-BEC crossover
M. L. Chiofalo, S. Giorgini, M. Holland
We develop a time-dependent mean-field theory to investigate the released momentum distribution and the released energy of an ultracold Fermi gas in the BCS-BEC crossover after the…
Molecular signatures in the structure factor of an interacting Fermi gas
R. Combescot, S. Giorgini, S. Stringari
The static and dynamic structure factors of an interacting Fermi gas along the BCS-BEC crossover are calculated at momentum transfer higher than the Fermi momentum.…
Correlation functions of a Lieb-Liniger Bose gas
G. E. Astrakharchik, S. Giorgini
The ground-state correlation functions of a one-dimensional homogeneous Bose system described by the Lieb-Liniger Hamiltonian are investigated by using exact quantum Monte Carlo te…
Momentum distribution of a Fermi gas of atoms in the BCS-BEC crossover
C. A. Regal, M. Greiner, S. Giorgini +2
We observe dramatic changes in the atomic momentum distribution of a Fermi gas in the region of the BCS-BEC crossover. We study the shape of the momentum distribution and the kinet…
Momentum distribution and condensate fraction of a Fermi gas in the BCS-BEC crossover
G. E. Astrakharchik, J. Boronat, J. Casulleras +1
By using the diffusion Monte Carlo method we calculate the one- and two-body density matrix of an interacting Fermi gas at T=0 in the BCS-BEC crossover. Results for the momentum di…
