    Equivalence of the train model of earthquake and boundary driven Edwards-Wilkinson interface

    A discretized version of the Burridge-Knopoff train model with (non-linear friction force replaced by) random pinning is studied in one and two dimensions. A scale free distribution of avalanches and the Omori...

    Classical Monte Carlo Simulation

    In Monte Carlo simulation, our primary goal is to calculate an observable physical quantity X of a thermodynamic system in thermal equilibrium with a heat bath at temperature T. A macroscopic thermodynamic system...

    Avalanches and Damage Clusters in Fracture Processes

    By simulating two-dimensional models of electric breakdown and fracture it is possible to characterize the rupture of disordered materials subject to an increasing external stress. We provide a review of numer...
