Description:
Author(s): X.-W. Guan, X.-G. Yin, A. Foerster, M. T. Batchelor, C.-H. Lee, and H.-Q. Lin 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-component Tomonaga-Luttinger liquid phase. The ratio ... [Phys. Rev. Lett. 111, 130401] Published Mon Sep 23, 2013
