Critical behaviour in three-state Potts antiferromagnets on a Bethe lattice

A rigorous method recently introduced for the solution of spin models on Bethe lattices is used to solve the three-state antiferromagnetic Potts model in an external field, and to find its phase diagram. Critical lines where the system undergoes first-order or second-order phase transitions are found, which are in complete qualitative agreement with recent results by Racz and Vicsek. Also new unexpected ordered phases are found.
