Reply to Skorik's Comment

TL;DR

This paper defends previous work on calculating transport properties in a Luttinger liquid with an impurity, clarifying that Skorik's criticism at finite voltage is unfounded and reaffirming the validity of their results.

Contribution

The authors clarify and defend their combined Bethe ansatz and kinetic equation approach against criticisms, confirming its correctness at finite voltage.

Findings

Skorik's critique is deemed inappropriate.

The original results remain valid at finite voltage.

No flaw exists in the authors' previous calculations.

Abstract

In a series of papers we combined the Bethe ansatz with a kinetic (Boltzmann) equation in order to compute exactly transport properties in a Luttinger liquid with an impurity. In a recent comment [cond-mat/9708163], Skorik claimed that while our results were correct in linear response, there was a ``serious flaw'' in our calculation at finite voltage. We explain here why Skorik's arguments are inappropriate, and that there is no flaw in our work [cond-mat/9408068; cond-mat/9505031; cond-mat/9503172].
