Phase separation in asymmetrical fermion superfluids
arXiv:cond-mat/0306694 · doi:10.1103/PhysRevLett.91.247002
Abstract
Motivated by recent developments on cold atom traps and high density QCD we consider fermionic systems composed of two particle species with different densities. We argue that a mixed phase composed of normal and superfluid components is the energetically favored ground state. We suggest how this phase separation can be used as a probe of fermion superfluidity in atomic traps.
