The free energy of the Potts model : from the continuous to the first-order transition region. ABSTRACT We present a large q expansion of the 2d q-states Potts model free energies up to order 9 in 1/ √ q. Its analysis leads us to an ansatz which, in the first-order region, incorporates properties inferred from the known critical regime at q = 4, and(More)
We develop an ansatz for expressing the free energy of the two dimensional q-states Potts model for q > 4 near its first order phase transition point. We notice that for the moderate values of q 15, the energy profile at the phase transition is not expressible as a sum of gaussians. We discuss how this affects the traditional finite size analysis of this(More)
