We analyze the properties of the q-state ferromagnetic Potts model for real q. The nature of the phase transition at the critical point is first-order for q=/=2, and second-order for q=2. The random-bond percolation limit q-->1, and its second-order-like transition, are not related to the previous behaviour since they arise from non-stable phases of the system. It is suggested that this property characterizes the model on high-dimensional lattices, too.

Abstract
We analyze the properties of the q-state ferromagnetic Potts model for real q. The nature of the phase transition at the critical point is first-order for q=/=2, and second-order for q=2. The random-bond percolation limit q-->1, and its second-order-like transition, are not related to the previous behaviour since they arise from non-stable phases of the system. It is suggested that this property characterizes the model on high-dimensional lattices, too.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
