The pair-contact process 2A ? 3A, 2A ? ? with diffusion of individual particles is a simple branching-annihilation process which exhibits a phase transition from an active to an absorbing phase with an unusual type of critical behaviour which had not been seen before. Although the model has attracted considerable interest during the past few years, it is not yet clear how its critical behaviour can be characterized and to what extent the diffusive pair-contact process represents an independent… 
Coupled two-species model for the pair contact process with diffusion.
A two-species representation for the PCPD is introduced in which single particles B and particle pairs A are dynamically coupled according to the stochastic reaction processes B+B→A, A→A+B,–A→∅, and A→B-B, with each particle type diffusing independently.
Phase transition in an exactly solvable reaction-diffusion process.
The model exhibits a phase transition at a particular point in the phase diagram which can be related to a condensation transition in a particular zero-range process and the corresponding critical exponents are determined.
Persistence as the order parameter in a generalized pair-contact process with diffusion
The question of the universality class of the pair-contact process with diffusion (PCPD) is revisited with an alternative approach. We study persistence in a generalized pair-contact process with
Pair Contact Process with Diffusion ( PCPD )
The Pair Contact Process with Diffusion (PCPD) is an out-ofequilibrium reaction diffusion model showing a phase transition between an absorbing and an active state. We study this model at a constant
Critical behaviour of continuous phase transitions with infinitely many absorbing states
A lattice gas model is proposed for the A2 + 2B2 → 2B2A reaction system with particle diffusion. In the model, A2 dissociates in the random dimer-filling mechanism and B2 dissociation is in the
Effects of diffusion in competitive contact processes on bipartite lattices
We investigate the influence of particle diffusion in the two-dimension contact process (CP) with a competitive dynamics in bipartite sublattices, proposed in [Phys. Rev. E 84, 011125 (2011)]. The
Universality-class crossover by a nonorder field introduced to the pair contact process with diffusion.
To investigate if diffusing particles are really indistinguishable from frozen particles in the sense of the renormalization group, numerically a variation of the PCPD is studied by introducing a nonorder field associated with infinitely many absorbing states and it is found that a crossover from thePCPD to DP occurs due to the non order field.
Phase Transition of the Pair Contact Process Model in a Fragmented Network
We investigate the phase transition of the pair contact process (PCP) model in a fragmented network. The network is formed by rewiring the link between two nearest neighbors to another randomly
Reaction–diffusion processes and non-perturbative renormalization group
This paper is devoted to investigating non-equilibrium phase transitions to an absorbing state, which are generically encountered in reaction–diffusion processes. It is a review, based on Canet,


The diffusive pair contact process and non-equilibrium wetting
The Langevin equation for the pair contact process with diffusion (PCPD) 2A->3A, 2A->0 can be mapped by a Cole-Hopf transformation to a Kardar-Parisi-Zhang equation in a potential which has been
Pair contact process with a particle source.
In the course of the paper, high-precision values for the critical exponents of the standard PCP are obtained, confirming directed-percolationlike scaling.

The results suggest that the transition might belong to a different universality class that has not been investigated before, and this is surprising since the model does not have an explicit parity-conserving symmetry.
Nonuniversality in the pair contact process with diffusion.
We study the static and dynamic behavior of the one dimensional pair contact process with diffusion. Several critical exponents are found to vary with the diffusion rate, while the order-parameter

Computer simulations in 1D yielded critical exponents consistent with directed percolation, for the first time placing a model with infinitely many absorbing states firmly in the directed-percolation universality class.
Phase transitions and correlations in the bosonic pair contact process with diffusion: exact results
The variance of the local density of the pair contact process with diffusion is investigated in a bosonic description. At the critical point of the absorbing phase transition (where the average
Critical properties of the reaction-diffusion model 2A-->3A, 2A-->0.
The steady-state phase diagram of the one-dimensional reaction-diffusion model 2A-->3A,2A-->0 is studied through the non-Hermitian density matrix renormalization group, where the value of beta/nu(perpendicular) is close to thevalue of the parity conserving universality class, in spite of the absence of local conservation laws.

Cluster mean-field approximations and Monte Carlo simulations predict a continuous phase transition for higher diffusion/coagulation rates as considered by the exact solution, and numerical evidence is given that the phase transition universality agrees with that of the annihilation-fission model with low diffusions.
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
Pair contact process in two dimensions.
We study the stationary properties of the two-dimensional pair contact process, a nonequilibrium lattice model exhibiting a phase transition to an absorbing state with an infinite number of
