Abstract: (Elsevier)
Statistical systems at second-order phase-transition points should exhibit conformal invariance at long distances. Their conformal properties can be analysed by investigating finite-size scaling behaviour. For integrable lattice models in two dimensions, methods are proposed to calculate, from the Bethe ansatz solution, the conformal anomaly c and all scaling dimensions. As an application results for the q -state Potts model and modified six-vertex models are presented.
