Stability of trapped fermionic gases with attractive interactions
arXiv:cond-mat/0602191 · doi:10.1103/PhysRevA.73.043616
Abstract
We present a unified overview, from the mean-field to the unitarity regime, of the stability of a trapped Fermi gas with short range attractive interactions. Unlike in a system of bosons, a Fermi gas is always stable in these regimes, no matter how large the particle number. However, when the interparticle spacing becomes comparable to the range of the interatomic interactions, instability is not precluded.
