    • Wilson Ratio of Fermi Gases in One Dimension 

      Guan, Xi-Wen; Yin, Xiangguo; Foerster, Angela; Batchelor, Murray T.; Lee, Chaohong; Lin, Hai-Qing (2013) [Journal article]
      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 ...
