Discontinuous transition in 2D Potts: I. Order-Disorder Interface convergence

Moritz Dober, Alexander Glazman, Sébastien Ott

We study a $q$-state Potts model on the square grid when $q>4$ at the point $T_c(q)$ of its (discontinous) transition. This model exhibits exactly $q+1$ extremal Gibbs measures: $q…
