• Spin Drag in Ultracold Fermi Mixtures with Repulsive Interactions 

    Duine, R. A.; Polini, Marco; Raoux, Arnaud; Stoof, H. T. C.; Vignale, Giovanni, 1957- (arXiv, 2010)
    We calculate the spin-drag relaxation rate for a two-component ultracold atomic Fermi gas with positive scattering length between the two spin components. In one dimension we find that it vanishes linearly with temperature. ...
