Thermal form-factor approach to dynamical correlation functions of integrable lattice models
Frank Göhmann, Michael Karbach, Andreas Klümper +2
We propose a method for calculating dynamical correlation functions at finite temperature in integrable lattice models of Yang-Baxter type. The method is based on an expansion of t…

On the thermodynamic limit of form factor expansions of dynamical correlation functions in the massless regime of the XXZ spin chain
K. K. Kozlowski
This work constructs a well-defined and operational form factor expansion in a model having a massless spectrum of excitations. More precisely, the dynamic two-point functions in t…
