We investigate the thermal quench of Ising and Potts models via Monte Carlo dynamics.We nd that the local distribution of the site-site interaction energy has the same form asin the equilibrium case, a result that allows us to dene an instantaneous temperature during the systems relaxation. We also nd that, after an undercritical quench, equals the heat bath temperature in a nite time, while the total system energy is stilldecreasing due to the coarsening process.

Abstract
We investigate the thermal quench of Ising and Potts models via Monte Carlo dynamics.We nd that the local distribution of the site-site interaction energy has the same form asin the equilibrium case, a result that allows us to dene an instantaneous temperature during the systems relaxation. We also nd that, after an undercritical quench, equals the heat bath temperature in a nite time, while the total system energy is stilldecreasing due to the coarsening process.File in questo prodotto:
