"Unbalanced strongly interacting Fermi gas"

Abstract
We study the zero temperature properties of a trapped polarized Fermi 
gas at unitarity by assuming phase separation between an unpolarized 
superfluid and a polarized normal phase. The effects of the interaction 
are accounted for using the formalism of quasiparticles to build up the 
equation of state of the normal phase. Our predictions for the 
Chandrasekhar-Clogston limit of critical polarization and for the 
density profiles, including the density jump at the interface, are 
confirmed with excellent accuracy by the recent experimental results. 
The role of interaction on the radial width of the minority component, 
on the gap of spectral functions, and on the spin oscillations in the 
normal phase is also discussed. Our analysis points out the Fermi liquid 
nature of these strongly interacting spin-polarized configurations.
