The dilute AL models and the integrable perturbations of unitary minimal CFTs
Abstract
Recently, a set of thermodynamic Bethe ansatz equations is proposed by Dorey, Pocklington and Tateo for unitary minimal models perturbed by φ1,2 or φ2,1 operator. We examine their results in view of the lattice analogues, dilute AL models at regime 1 and 2. Taking M5,6+φ1,2 and M3,4+φ2,1 as the simplest examples, we will explicitly show that the conjectured TBA equations can be recovered from the lattice model in a scaling limit.
