Linear and nonlinear conductivity of disordered Luttinger liquids

I will consider low energy charge transport in one-dimensional electron systems with short range interactions under the influence of a random potential. Combining RG and instanton methods, I will calculate the nonlinear ac conductivity and discuss the crossover between the nonanalytic field dependence of the electric current at zero frequency and the linear ac conductivity at small electric fields and finite frequency.
