Pairing fluctuation effects on the single-particle spectra for the superconducting state
P. Pieri, L. Pisani, G. C. Strinati
Single-particle spectra are calculated in the superconducting state for a fermionic system with an attractive interaction, as functions of temperature and coupling strength from we…

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…
