Abstract

摘要

The Potts model—a simple statistical-mechanical system—plays an important role in the theory of critical phenomena and finds various application in condensed-matter physics and beyond. The ferromagnetic Potts model is now well understood, thanks to universality. In two dimensions, much exact information is available due to analytic solution and the development of conformal field theory, via its connection with Coulomb-gas theory and Schramm-Loewner evolution (SLE). In this seminar, I shall report two recent studies of the q-state Potts antiferromagnet. I shall present argument as well as numerical evidence that the Potts antiferromagnet with arbitrarily large values of q can have a finite-temperature phase transition on some families of two-dimensional lattices. I will also demonstrate that the emergent continuous symmetry can occur in a series of three-dimensional Potts model.
