We consider the quantum corrections to the conductivity of fermions interacting via a Chern-Simons gauge field, and concentrate on the Hartree-type contributions. The first-order Hartree approximation is only valid in the limit of weak coupling \lambda to the gauge field, and results in an antilocalizing conductivity correction, \sim \lambda^2 g \ln^2 T (g is the conductance). In the case of strong coupling, an infinite summation of higher-order terms is necessary, including both the virtual… 

Quantum interference of hydrodynamic modes in a dirty marginal Fermi liquid

We study the electrical transport of a two-dimensional non-Fermi liquid with disorder, and we determine both the semiclassical dc conductivity and the first quantum correction. We consider a system
