Finite Temperature Correlation Functions in Integrable QFT

High Energy Physics - Theory 2009-10-31 v1 Condensed Matter

Abstract

Finite temperature correlation functions in integrable quantum field theories are formulated only in terms of the usual, temperature-independent form factors, and certain thermodynamic filling fractions which are determined from the thermodynamic Bethe ansatz. Explicit expressions are given for the one and two-point functions.
