Abstract. When the two dimensional q-color Potts model in the square lattice is quenched at zero temperature with Glauber dynamics, the energy decreases in time following an Allen-Cahn power law, and the system converges to a phase with energy higher than the ground state energy after an arbitrary large time when q>4. At low but finite temperature, it cesses to obey the power-law regime and orders after a very long time, which increases with q, and before which it performs a domain growth… 
Low-temperature universal dynamics of the bidimensional Potts model in the large q limit
We study the low temperature quench dynamics of the two-dimensional Potts model in the limit of a large number of states, q ≫ 1. We identify a q-independent crossover temperature (the pseudo
How many phases nucleate in the bidimensional Potts model?
We study the kinetics of the two-dimensional q > 4-state Potts model after a shallow quench to a temperature slightly below the critical one and above the pseudo spinodal. We use numerical methods
Long-term ordering kinetics of the two-dimensional q-state Potts model.
The nonequilibrium dynamics of the q-state Potts model in the square lattice is studied, after a quench to subcritical temperatures, by means of a continuous time Monte Carlo algorithm and the existence of different dynamical regimes is found, according to quench temperature range.
Multinucleation in the first-order phase transition of the 2d Potts model
Using large-scale numerical simulations we studied the kinetics of the 2d q-Potts model for q > 4 after a shallow subcritical quench from a high-temperature homogeneous configuration. This protocol

Metastability in the Potts model: exact results in the large q limit
We study the metastable equilibrium properties of the two-dimensional Potts model with heat-bath transition rates using a novel expansion. The method is especially powerful for large number of state
Dinámica de relajación del modelo de Potts de q estados bidimensional
We analyze the bidimensional q-state Potts model, a paradigmatic model in the study of Statistical Mechanics of Critical Phenomena and Phase Transitions, which presents first (q > 4) and second order
A lattice model approach to the morphology formation from ternary mixtures during the evaporation of one component
Abstract Stimulated by experimental evidence in the field of solution-born thin films, we study the morphology formation in a three state lattice system subjected to the evaporation of one component.
Quantitative analysis of phase formation and growth in ternary mixtures upon evaporation of one component
We perform a quantitative analysis of Monte–Carlo simulations results of phase separation in ternary blends upon evaporation of one component. Specifically, we calculate the average domain size and


Domain growth in the field-theoretic version of the Potts model.
The results are in agreement with those obtained from recent Monte Carlo studies of the discrete Potts model with stochastic dynamics, and indicate that the domain growth kinetics of the two-dimensional q-state Pottsmodel is characterized by a Lifshitz-Allen-Cahn kinetic exponent n=(1/2, independent of q for a nonconserved order parameter.
Universality of ordering dynamics in conserved multicomponent systems.
A comparative study is performed of the ordering dynamics and spinodal decomposition processes in two-dimensional two-state and three-state ferromagnetic Potts models with conserved order parameter and the growth law that describes the time-evolution of the linear length scale of the ordered domains is found to be algebraic.

The time-dependent two-point correlation functions for general $q$-state Potts model are calculated and establish a correspondence of this model to the Ising model evolving with a fixed magnetization.
Theory of phase-ordering kinetics
The theory of phase-ordering dynamics that is the growth of order through domain coarsening when a system is quenched from the homogeneous phase into a broken-symmetry phase, is reviewed, with the
Domain-growth kinetics for the Q-state Potts model in two and three dimensions.
The grain-size distribution for several values of Q in both two and three dimensions is determined and compared with the results for grain growth in real polycrystalline materials.
Metastability in zero-temperature dynamics: statistics of attractors
The zero-temperature dynamics of simple models such as Ising ferromagnets provides, as an alternative to the mean-field situation, interesting examples of dynamical systems with many attractors
Freezing in Ising ferromagnets.
This work investigates the final state of zero-temperature Ising ferromagnets that are endowed with single-spin-flip Glauber dynamics, and finds that the ground state is generally not reached for zero initial magnetization.
Potts model at the critical temperature
It is shown that the two-dimensional q-component Potts model is equivalent to a staggered ice-type model. It is deduced that the model has a first-order phase transition for q>4, and a higher-order
