We present a general definition of damage spreading in a pair of models. Using this general framework, one can define damage spreading in an objective manner that does not depend on the particular dynamic procedure that is being used. The formalism can be used for any spin-model or cellular automaton, with sequential or parallel update rules. At this point we present its application to the Domany–Kinzel cellular automaton in one dimension, this being the simplest model in which damage spreading… 
Percolation and Internet Science
This review presents a model of opinion spreading, the role of the topology of the network to induce coherent oscillations and the influence of risk perception for stopping epidemics, and introduces the open problem of controlling percolation and other processes on distributed systems.
Damage spreading in random field systems
An effective field theory for damage spreading in random-field systems is derived and it is found that the random field influences the spreading transition by two different mechanisms with opposite effects.
Damage Spreading in a 2D Ising Model with Swendsen–Wang Dynamics
Damage spreading for Ising cluster dynamics is investigated numerically by using random numbers in a way that conforms with the notion of submitting the two evolving replicas to the same thermal
The inactive-active phase transition in the noisy additive (exclusive-or) probabilistic cellular automaton
The critical behavior of the noisy additive cellular automaton is characterized by mean field analysis and finite-size scaling and it is shown that its phase transition belongs to the directed percolation universality class of critical behavior.
In an Ising model with spin-exchange dynamics damage always spreads
We investigate the spreading of damage in Ising models with Kawasaki spin-exchange dynamics which conserves the magnetization. We first modify a recent master equation approach to account for dynamic
Roughness exponent in the Domany-Kinzel cellular automaton
We propose a method to detect phase transitions in discrete lattice models based on the roughness exponent. This approach is applied to the one-dimensional Domany-Kinzel cellular automaton (CA). Our
Chaos in a Simple Cellular Automaton Model of a Uniform Society
In this work we study the collective behavior in a model of a simplified homogeneous society. Each agent is modeled as a binary “perceptron”, receiving neighbors’ opinions as inputs and outputting
Critical Phenomena in Nonequilibrium Systems
This review addresses recent developments in nonequilibrium statistical physics. Focusing on phase transitions from fluctuating phases into absorbing states, the universality class of directed


On damage-spreading transitions
We study the damage-spreading transition in a generic one-dimensional stochastic cellular automaton with two inputs (Domany-Kinzel model). Using an original formalism for the description of the
Are damage spreading transitions generically in the universality class of directed percolation?
We present numerical evidence for the fact that the damage spreading transition in the Domany-Kinzel automaton found by Martinset al. is in the same universality class as directed percolation. We
Evidence for a new phase in the Domany-Kinzel cellular automaton.
A generalized version (including anisotropy) of the stochastic one-dimensional cellular automaton studied by Domany and Kinzel is considered, which recovers Wolfram-like deterministic cellular automata as particular cases and recognizes the Glauber dynamics, for example, as a special case of a CA.
Comparative study of damage spreading in the Ising model using heat-bath, glauber, and metropolis dynamics
AbstractWe study the time evolution of two configurations of the Ising model submitted to heat-bath (HB), Glauber (G), and two types of Metropolis (M and $$\tilde M$$ ) dynamics, analyzing the damage
Time-dependent thermodynamic properties of the Ising model from damage spreading
The relationship between damage spreading and static thermodynamic properties in the Ising model developed by Coniglioet al. is here extended to include time-dependent thermodynamic quantities. We
Time-dependent perturbation theory for nonequilibrium lattice models.
We develop a time-dependent perturbation theory for nonequilibrium interacting particle systems. We focus on models such as the contact process which evolve via destruction and autocatalytic creation
Directed compact percolation: cluster size and hyperscaling
Exact recurrence relations are obtained for the length and size distributions of compact directed percolation clusters on the square lattice. The corresponding relation for the moment generating
