Reply to a comment on "A Comparison Between Broad Histogram and Multicanonical Methods"
A. R. Lima, T. J. P. Penna, P. M. C. de Oliveira
This is a reply to the comment by M. Kastner and M. Promberger [cond-mat/0011516] on the paper published in J. Stat. Phys. 99, 691 (2000) and also in cond-mat/0002176. We show that…
Mean Field theory for a driven granular gas of frictional particles
Raffaele Cafiero, Stefan Luding
We propose a mean field (MF) theory for a homogeneously driven granular gas of inelastic particles with Coulomb friction. The model contains three parameters, a normal restitution…
Kinetic roughening with anysotropic growth rules
Raffaele Cafiero
Inspired by the chemical etching processes, where experiments show that growth rates depending on the local environment might play a fundamental role in determining the properties…
Fractal Growth from Local Instabilities
Raffaele Cafiero, Guido Caldarelli
We study, both with numerical simulations and theoretical methods, a cellular automata model for continuum equations describing growth processes in the presence of an external flux…
Phase separation in a chaotic flow
Ludovic Berthier, Jean-Louis Barrat, Jorge Kurchan
The phase separation between two immiscible liquids advected by a bidimensional velocity field is investigated numerically by solving the corresponding Cahn-Hilliard equation. We s…
Two-dimensional Granular Gas of Inelastic Spheres with Multiplicative Driving
Raffaele Cafiero, Stefan Luding, Hans Jürgen Herrmann
We study a two-dimensional granular gas of inelastic spheres subject to multiplicative driving proportional to a power of the local particle velocity .…
