Wilson Ratio of Fermi gases in One Dimension

Guan, Xi-Wen; Yin, X.-G.; Foerster, Angela; Batchelor, Murray; Lee, C.-H.; Lin, H.-Q.


We calculate the Wilson ratio of the one-dimensional Fermi gas with spin imbalance. The Wilson ratio of attractively interacting fermions is solely determined by the density stiffness and sound velocity of pairs and of excess fermions for the two-componen
