We study the motion of elastic networks driven over a random substrate. Our model which includes local friction forces leads to complex dynamical behavior. We find a transition to a sliding state which belongs to a new universality class. The phase diagram comprises of a pinned state, a...

Dynamical critical exponents of three surface reaction models - a monomer-monomer process and two variants of the dimer-dimer process - which exhibit discontinuous kinetics phase transitions (KPTs) are evaluated. The obtained exponents differ from those characteristic of continuous KPTs and...

The standard Vicsek model (SVM) is a minimal non-equilibrium model of self-propelled particles that appears to capture the essential ingredients of critical flocking phenomena. In the SVM, particles tend to align with each other and form ordered flocks of collective motion; however,...

The spreading of damage in the Ising ferromagnet in two-dimensional confined geometries of size L×M(L⪡M) close to the critical temperature is studied by means of computer simulations. Imposing both, periodic and open boundary conditions along the M-direction, the influence of the interfaces...

The classic Katz–Lebowitz–Spohn (KLS) model is a lattice gas driven by an external field. In this paper, we study the critical behavior of the KLS model driven by an oscillatory field of strength E and period τ by means of both, Monte Carlo simulations and a coupled-map-lattice mean-field...

An Ising model for damage spreading with a probability of damage healing (q=1-p) is proposed and studied by means of Monte Carlo simulations. In the limit p→1, the new model is mapped to the standard Ising model. It is found that, for temperatures above the Onsager critical temperature (TC),...

In a forest fire model with immune trees (FFMIT) recently proposed by Drossel and Schwabl (Physica A 199 (1993) 183), the sites of the lattice are either empty, a tree or a burning tree, and at each time step the system is updated in parallel according to the following rules: (i) A burning tree...

The spatiotemporal behavior of an initially corrugated interface in the two-dimensional driven lattice gas (DLG) model with attractive nearest-neighbors interactions is investigated via Monte Carlo simulations. By setting the system in the ordered phase, with periodic boundary conditions along...

We studied damage spreading in a Driven Lattice Gas (DLG) model as a function of the temperature T, the magnitude of the external driving field E, and the lattice size. The DLG model undergoes an order–disorder second-order phase transition at the critical temperature Tc(E), such that the...

The spreading of globally distributed damage was studied in two variants of an irreversible dimer-dimer surface reaction model of the type 12A2 + B2 → B2A. The first model (model M1) neglects desorption of B2. On the contrary, the second version (model M3) takes this process into account. Both...
