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…
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…
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…
Scattering length for composite bosons in the BCS-BEC crossover
P. Pieri, G. C. Strinati
The present manuscript concerns the calculation of the boson-boson scattering length for the composite bosons that form as bound-fermion pairs in the strong-coupling limit of the B…
Time-dependent Gross-Pitaevskii equation for composite bosons as the strong-coupling limit of the fermionic BCS-RPA approximation
G. C. Strinati, P. Pieri
The linear response to a space- and time-dependent external disturbance of a system of dilute condensed composite bosons at zero temperature, as obtained from the linearized versio…
