Exact results for the 1D interacting Fermi gas with arbitrary polarization
arXiv:cond-mat/0506264 · doi:10.1088/1742-6596/42/1/002
Abstract
We investigate the 1D interacting two-component Fermi gas with arbitrary polarization. Exact results for the ground state energy, quasimomentum distribution functions, spin velocity and charge velocity reveal subtle polarization dependent quantum effects.
7 pages, 3 figures, final published version without the discussion of harmonic trapping (to be taken up elsewhere). The effect of a magnetic-like field term on pairing and phase transtions has been discussed via the TBA approach in cond-mat/0702191
