On the $R P^{N - 1}$ and $C P^{N - 1}$ universality classes

Youness Diouane, Noel Lamsen, Gesualdo Delfino

We recently determined the exact fixed point equations and the spaces of solutions of the two-dimensional $R P^{N - 1}$ and $C P^{N - 1}$ models using scale invariant scattering theory.…

Critical points in coupled Potts models and correlated percolation

Noel Lamsen, Youness Diouane, Gesualdo Delfino

We use scale invariant scattering theory to exactly determine the renormalization group fixed points of a $q$ -state Potts model coupled to an $r$ -state Potts model in two dimension…

Critical points in the $C P^{N - 1}$ model

Youness Diouane, Noel Lamsen, Gesualdo Delfino

We use scale invariant scattering theory to obtain the exact equations determining the renormalization group fixed points of the two-dimensional $C P^{N - 1}$ model, for $N$ real. Als…

Absence of nematic quasi-long-range order in two-dimensional liquid crystals with three director components

Gesualdo Delfino, Youness Diouane, Noel Lamsen

The Lebwohl-Lasher model describes the isotropic-nematic transition in liquid crystals. In two dimensions, where its continuous symmetry cannot break spontaneously, it is investiga…

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

Gesualdo Delfino, Noel Lamsen

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 poi…

Critical points of coupled vector-Ising systems. Exact results

Gesualdo Delfino, Noel Lamsen

We show that scale invariant scattering theory allows to exactly determine the critical points of two-dimensional systems with coupled $O (N)$ and Ising order pameters. The results…

Critical lines in the pure and disordered $O (N)$ model

Gesualdo Delfino, Noel Lamsen

We consider replicated $O (N)$ symmetry in two dimensions within the exact framework of scale invariant scattering theory and determine the lines of renormalization group fixed poin…
