The Potts model is a generalization of the Ising model, with \(q\) different state available for every lattice site. For \(q>4\) the system undergoes a first order phase transition, whose control parameter is the temperature. The presence of multiple equilibrium phase can slow down the dynamics towards equilibrium.
We investigated the dynamical metastability of the Potts model on a square lattice after a quench just below the discontinuous transition temperature. By mean of the correlation function of the system we identified the metastable realization and we have studied their energy distribution and the dependence of the spinodal temperature with the system size, in order to assert whether or not metastability is a finite-size effect.
