Form factor approach to dynamical correlation functions in critical models
N. Kitanine, K. K. Kozlowski, J. M. Maillet +2
We develop a form factor approach to the study of dynamical correlation functions of quantum integrable models in the critical regime. As an example, we consider the quantum non-li…

Surface free energy of the open XXZ spin-1/2 chain
K. K. Kozlowski, B. Pozsgay
We study the boundary free energy of the XXZ spin-$\tf{1}{2}$ chain subject to diagonal boundary fields. We first show that the representation for its finite Trotter number approxi…
