Recently Dantas, Oliveira and Stilck (2007 J. Stat. Mech. P08009) studied how the one-dimensional diffusive contact process crosses over from the critical behavior of directed percolation to an effective mean field behavior when the diffusion rate is sent to infinity. They showed that this crossover can be described in terms of a crossover exponent ϕ, finding the boundaries 3≤ϕ≤4 in one spatial dimension. In the present work we refine and extend this result up to four spatial dimensions by…

A new method is proposed to derive the critical probability, below which forest fires do not expand to infinitely large area, using percolation theory and mean-field approximation.

The crossover behavior of various models exhibiting phase transition to absorbing phase with parity conserving class has been investigated by numerical simulations and cluster mean-field method and the resulting models show a diversity within the DP universality class in one dimension.


Revisiting the one-dimensional diffusive contact process
In this work we study the one-dimensional contact process with diffusion using two different approaches to estimate the critical properties of this model: the supercritical series expansion and
On the nonequilibrium phase transition in reaction-diffusion systems with an absorbing stationary state
It is pointed out that chemical reactions which show an absorbing stationary state in the master-equation approach (e.g. Schlögl's first reaction) exhibit nevertheless a second order phase transition
Directed percolation criticality in turbulent liquid crystals.
This work experimentally investigates the critical behavior of a phase transition between two topologically different turbulent states of electrohydrodynamic convection in nematic liquid crystals, providing the first clear and comprehensive experimental evidence of an absorbing phase transition in this prominent nonequilibrium universality class.
On possible experimental realizations of directed percolation
Directed percolation is one of the most prominent universality classes of nonequilibrium phase transitions and can be found in a large variety of models. Despite its theoretical success, no
Non-equilibrium critical phenomena and phase transitions into absorbing states
This review addresses recent developments in non-equilibrium statistical physics. Focusing on phase transitions from fluctuating phases into absorbing states, the universality class of directed
Field-Theory Approaches to Nonequilibrium Dynamics
It is explained how field-theoretic methods and the dynamic renormalisation group (RG) can be applied to study the universal scaling properties of systems that either undergo a continuous phase
Asymptotic behavior of basic contact process with rapid stirring
AbstractIn this paper we consider the basic contact process with infection rate λ and stirring rateD. We study the asymptotic behavior of the critical value $$\lambda _c (D)$$ and survival
Universality classes in nonequilibrium lattice systems
This work is designed to overview our present knowledge about universality classes occurring in nonequilibrium systems defined on regular lattices. In the first section I summarize the most important
Phase transitions of cellular automata
Cellular automata (CA) are simple mathematical models of the dynamics of discrete variables in discrete space and time, with applications in nonequilibrium physics, chemical reactions, population
Universal scaling behavior of non-equilibrium phase transitions
One of the most impressive features of continuous phase transitions is the concept of universality, that allows to group the great variety of different critical phenomena into a small number of
