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.

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

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
