Viscosity of a two-dimensional Fermi liquid
arXiv:cond-mat/0603184
Abstract
Shear viscosity of a two-dimensional Fermi liquid is found to be a nonanalytic function of temperature. In contrast to the quasiparticle lifetime that is determined by the forward-scattering processes, the main contribution to the viscosity arises from the quasiparticle scattering in the Cooper channel. The viscosity is enhanced by the logarithmic singularity of the vertex part. This singular behavior can manifest itself in the two-dimensional electron transport, and in the momentum relaxation of fermions in atomic traps.
