Abstract

Linear response is investigated for the sine-Gordon chain. This is a direct application of a method introduced in a previous paper. The transfer integral method is applied. The Fokker-Planck equation is solved with a kind of decoupling approximation of the phase space distribution function. The frequency dependent mobility is obtained. It has a remarkable peak at a finite frequency and a small finite mobility at ω=0 for an appropriate choice of the damping constant.
