摘要：

The nonlinear conductance for tunnelling through an impurity in a Luttinger liquid and the nonequilibrium DC current noise are calculated exactly for low temperatures. We present a pedestrian pathway towards the exact solution which is based on analytic properties and on a duality between weak and strong backscattering. The prefactor of the T-2 enhancement is shown to be universally expressed in terms of zero temperature properties. Copyright (C) 1996 Published by Elsevier Science Ltd
