In this paper we introduce a very simple model exhibiting slow relaxation, typical of glassy systems. We show both numerical and analytically the slow nature of the relaxation process; in particular, we obtain stretched-exponential and power law curves for the energy relaxation depending on the parameter values and/or on the considered approximation in the analytical approach.

Abstract
In this paper we introduce a very simple model exhibiting slow relaxation, typical of glassy systems. We show both numerical and analytically the slow nature of the relaxation process; in particular, we obtain stretched-exponential and power law curves for the energy relaxation depending on the parameter values and/or on the considered approximation in the analytical approach.File in questo prodotto:
