Rotationally driven gas of inelastic rough spheres
R. Cafiero, S. Luding, H. J. Herrmann
We study a two-dimensional gas of inelastic rough spheres, driven on the rotational degrees of freedom. Numerical simulations are compared to mean-field (MF) predictions with surpr…
Damaging and Cracks in Thin Mud Layers
Raffaele Cafiero, Guido Caldarelli, Andrea Gabrielli
We present a detailed study of a two-dimensional minimal lattice model for the description of mud cracking in the limit of extremely thin layers. In this model each bond of the lat…
Dynamical phases and hysteresis in a simple one-lane traffic model
M. Antoni, R. Cafiero
A two parameter model for single lane car-following is introduced and its equilibrium and non-equilibrium properties are studied. Despite its simplicity, this model exhibits a rich…
Fractal Growth with Quenched Disorder
L. Pietronero, R. Cafiero, A. Gabrielli
In this lecture we present an overview of the physics of irreversible fractal growth process, with particular emphasis on a class of models characterized by {\em quenched disorder}…
Damage-Spreading in Self-Organized Critical Systems
Raffaele Cafiero, Angelo Valleriani, Josè Luis Vega
We study the behavior under perturbations of different versions of Bak-Sneppen (BS) model in 1 + 1 dimension. We focus our attention on the damage-spreading features of the BS mode…
