Thermodynamical Bethe Ansatz analysis in an SU(2)xU(1) symmetric sigma-model

Janos Balog, Peter Forgacs

Four different types of free energies are computed by both thermodynamical Bethe Ansatz (TBA) techniques and by weak coupling perturbation theory in an integrable one-parameter def…

Negative Screenings in Conformal Field Theory and 2D Gravity: The Braiding Matrix

J. Rasmussen, J. Schnittger

We consider an extension of the Coulomb gas picture which is motivated by Liouville theory and contains negative powers of screening operators on the same footing as positive ones.…
