Is demagnetization an efficient optimization method?
S. Zapperi, F. Colaiori, L. Dante +4
Demagnetization, commonly employed to study ferromagnets, has been proposed as the basis for an optimization tool, a method to find the ground state of a disordered system. Here we…
Crystal vs glass formation in lattice models with many coexisting ordered phases
Mario J. de Oliveira, Alberto Petri, Tania Tome
We present here new evidence that after a quench the planar Potts model on the square lattice relaxes towards a glassy state if the number of states q is larger than four. By extra…
Lattice models of disorder with order
Alberto Petri
This paper describes the use of simple lattice models for studying the properties of structurally disordered systems like glasses and granulates. The models considered have crystal…
Glassy states in lattice models with many coexisting crystalline phases
M. J. de Oliveira, A. Petri, T. Tome
We study the emergence of glassy states after a sudden cooling in lattice models with short range interactions and without any a priori quenched disorder. The glassy state emerges…
A microscopic 2D lattice model of dimer granular compaction with friction
C. Fusco, A. Fasolino, P. Gallo +2
We study by Monte Carlo simulation the compaction dynamics of hard dimers in 2D under the action of gravity, subjected to vertical and horizontal shaking, considering also the case…
Cumulants of the three state Potts model and of nonequilibrium models with C3v symmetry
Tania Tome, Alberto Petri
The critical behavior of two-dimensional stochastic lattice gas models with C3v symmetry is analyzed. We study the cumulants of the order parameter for the three state (equilibrium…
Stretched exponential relaxation in a diffusive lattice model
C. Fusco, P. Gallo, A. Petri +1
We studied the single dimer dynamics in a lattice diffusive model as a function of particle density in the high densification regime. The mean square displacement is found to be su…
Random sequential adsorption and diffusion of dimers and k-mers on a square lattice
C. Fusco, P. Gallo, A. Petri +1
We have performed extensive simulations of random sequential adsorption and diffusion of -mers, up to in two dimensions with particular attention to the case . We foc…
Clustering and Non-Gaussian Behavior in Granular Matter
A. Puglisi, V. Loreto, U. Marini Bettolo Marconi +2
We investigate the properties of a model of granular matter consisting of Brownian particles on a line subject to inelastic mutual collisions. This model displays a genuine the…
