The three-state Potts antiferromagnet on plane quadrangulations

Jian-Ping Lv, Youjin Deng, Jesper Lykke Jacobsen +1

We study the antiferromagnetic 3-state Potts model on general (periodic) plane quadrangulations $\Gamma$. Any quadrangulation can be built from a dual pair $(G,G^{\ast })$. Based on the duali…
