Description
I will give an introduction to transport phenomena and transport calculations in non-relativistic Fermi liquids. Such systems encompass interacting electron gases in the hydrodynamic regime, which has recently been accessed experimentally, but also atomic quantum gases. In particular, I will present calculations of the shear viscosity within kinetic theory at finite temperature. I will then discuss in more detail the structure of quasiparticle scattering in the presence of a Fermi surface in two-dimensional systems, which reveals a parity-dependence of relaxation rates. Such an odd-even effect gives rise to a new transport regime with long-lived odd-parity modes in addition to hydrodynamic ones, and the talk will conclude by discussing signatures of this regime in the collective mode spectrum.
