摘要: Linear response is investigated for the sine-Gordon chain. This a direct application of method introduced in previous paper. 1) The transfer integral applied. Fokker-Planck equation solved with kind decoupling approximation phase space distribution function. frequency dependent mobility obtained. It has remarkable peak at finite and small ω=0 an appropriate choice damping constant.
