Quasi-particle properties of trapped Fermi gases
Luca Giorgetti, Luciano Viverit, Giorgio Gori +3
We develop a consistent formalism in order to explore the effects of density and spin fluctuations on the quasi-particle properties and on the pairing critical temperature of a tra…
Pairing fluctuations in trapped Fermi gases
Luciano Viverit, Georg M. Bruun, Anna Minguzzi +1
Fluctuations of the amplitude of the order parameter govern the properties of superconducting systems close to the critical transition temperature. In the BCS regime we examine the…
Ground-state properties of a dilute Bose-Fermi mixture
L. Viverit, S. Giorgini
We investigate the properties of a dilute boson-fermion mixture at zero temperature. The ground-state energy of the system is calculated to second order in the Bose-Fermi coupling…
Boson induced s-wave pairing in dilute boson-fermion mixtures
L. Viverit
We show that in dilute boson-fermion mixtures with fermions in two internal states, even when the bare fermion-fermion interaction is repulsive, the exchange of density fluctuation…
