Extracting the condensate density from projection experiments with Fermi gases
A. Perali, P. Pieri, G. C. Strinati
A debated issue in the physics of the BCS-BEC crossover with trapped Fermi atoms is to identify characteristic properties of the superfluid phase. Recently, a condensate fraction w…
Comparison between a diagrammatic theory for the BCS-BEC crossover and Quantum Monte Carlo results
P. Pieri, L. Pisani, G. C. Strinati
Predictions for the chemical potential and the excitation gap recently obtained by our diagrammatic theory for the BCS-BEC crossover in the superfluid phase are compared with novel…
Popov approximation for composite bosons in the BCS-BEC crossover
P. Pieri, G. C. Strinati
Theoretical treatments of the BCS-BEC crossover need to provide as accurate as possible descriptions of the two regimes where the diluteness condition applies, either in terms of t…
Broad versus narrow Fano-Feshbach resonances in the BCS-BEC crossover with trapped Fermi atom
S. Simonucci, P. Pieri, G. C. Strinati
With reference to the broad and narrow Fano-Feshbach resonances of 6Li at about 822 G and 543 G, we show that for the broad resonance a molecular coupled-channel calculation can be…
Conserving and gapless approximations for the composite bosons in terms of the constituent fermions
G. C. Strinati, P. Pieri
A long-standing problem with the many-body approximations for interacting condensed bosons has been the dichotomy between the ``conserving'' and ``gapless'' approximations, which e…
BCS-BEC crossover at finite temperature in the broken-symmetry phase
P. Pieri, L. Pisani, G. C. Strinati
The BCS-BEC crossover is studied in a systematic way in the broken-symmetry phase between zero temperature and the critical temperature. This study bridges two regimes where quantu…
