Popis:	We investigate the non-equilibrium dynamics of the 2D Potts model on the square lattice after a quench below the discontinuous transition point. By means of numerical simulations of systems with q =12,24 and 48 we observe the onset of a stationary regime below the temperature-driven transition, in a temperature interval decreasing with the system size and increasing with q. These results obtained dynamically agree with those obtained from the analytical continuation of the free energy (Meunier and Morel, 2000), from which metastability in the 2D Potts model results to be a finite size effect. Comment: 6 pages, 4 figures. Different method for the estimation of the metastable endpoints in sec III and minor corrections. Updated bibliography. Conclusions and Introduction unchanged
