Finite-Temperature Phase Transition in a Class of Four-State Potts Antiferromagnets. Physical Review Letters, 107(15), 150601.0031-9007https://hdl.handle.net/10016/33102We argue that the four-state Potts antiferromagnet has a finite-temperature phase transition on any Eulerian plane triangulation in which one sublattice consists of vertices of degree 4. We furthermore predict the universality class of this transition. We then present transfer-matrix and Monte Carlo data confirming these predictions for the cases of the Union Jack and bisected hexagonal lattices.5eng© 2011 American Physical Societyresearch articleIngeniería IndustrialMatemáticashttps://doi.org/10.1103/PhysRevLett.107.150601open access15060115Physical Review Letters107AR/0000009453
