On the phase diagram of the random bond $q$-state Potts model

Abstract

We consider the two-dimensional random bond $q$-state Potts model within the recently introduced exact framework of scale invariant scattering, exhibit the line of stable fixed points induced by disorder for arbitrarily large values of $q$, and examine the renormalization group pattern for $q>4$, when the transition of the pure model is first order.
