Finite temperature correlation functions in integrable models: derivation of the semiclassical limit from the formfactor expansion

B. L. Altshuler, A. M. Tsvelik

We propose an approach to the problem of finite temperature dynamical correlation functions in integrable one-dimensional models with a spectral gap. The approach is based on the a…
