摘要：
We consider low-energy charge transport in one-dimensional electron systems with short-range interactions under the influence of a random potential. Combining renormalization group and instanton methods, we 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.
