Off equilibrium dynamics and aging in unfrustrated systems

Abstract

We analyse the Langevin dynamics of the random walk, the scalar field, the\nX-Y model and the spinoidal decomposition. We study the deviations from the\nequilibrium dynamics theorems (FDT and homogeneity), the asymptotic behaviour\nof the systems and the aging phenomena. We compare the results with the\ndynamical behaviour of (random) spin-glass mean-field models.\n
