Ferro-Nematic ground state of the dilute dipolar Fermi gas (2009)

Abstract
It is shown that a homogeneous two-component Fermi gas with (long range) dipolar and short-range isotropic interactions has a {\em ferro-nematic} phase for suitable values of the dipolar and short-range coupling constants. The ferro-nematic phase is characterized by having a non-zero magnetization and long range orientational uniaxial order. The Fermi surface of spin up (down) component is elongated (compressed) along the direction of the magnetization.. Comment: 4 pages, 4 figures. v2 contains a significant revision of version v1 which contained some incorrect results. v2 includes a detail discussion of the phase diagram (and of the degree of polarization of the ferro-nematic phase) including an estimate of the critical couplings. It supersedes the results presented in v1; Version v3 has minor changes
