Description

Finite temperature dynamical correlation functions of Yang-Baxter integrable quantum chains can be represented by thermal form-factor series. These are series in which every term is expressed in terms of the spectral data and the form factors of an appropriately defined dynamical quantum transfer matrix. We review the construction and exemplify its usefulness with the discussion of the leading term of the space-like asymptotic of the transverse correlation functions of the XXZ chain at finite temperature. This is a joint work with F. Göhmann
