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 experiment is known which clearly reproduces the critical exponents of directed percolation. The present work compares suggested experiments and discusses possible reasons why the observation of the critical exponents of directed percolation is obscured or even impossible. 
Nonequilibrium phase transition on a randomly diluted lattice.
It is shown that the interplay between geometric criticality and dynamical fluctuations leads to a novel universality class of the contact process on a randomly diluted lattice that is characterized by unconventional activated (exponential) dynamical scaling and strong Griffiths effects.
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.

It is found that the critical exponent associated with the order parameter (percolation probability) is beta=(1-1/square root[5])/2=0.276 486(8), in remarkable agreement with the best current numerical estimate.
Block scaling in the directed percolation universality class
The universal behaviour of the directed percolation universality class is well understood—both the critical scaling and the finite size scaling. This paper focuses on the block (finite size) scaling
Universality of the contact process with random dilution
We present quasistationary simulations of the two-dimensional contact process with quenched disorder included through the random dilution of a fraction of the lattice sites (these sites are not
Yang–Lee zeros for a nonequilibrium phase transition
Equilibrium systems which exhibit a phase transition can be studied by investigating the complex zeros of the partition function. This method, pioneered by Yang and Lee, has been widely used in
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
Multicritical behaviour of the diluted contact process
We study a contact process on a two-dimensional square lattice which is diluted by randomly removing bonds with probability p. For p<1/2 and varying birth rate λ the model was shown to exhibit a
Explosive phase transitions in percolation processes
Percolation processes are well studied in physics. In theoretical physics, directed percolation (DP) is a representative of a well-known universality class of continuous phase transitions [1]. DP has
Strong disorder fixed point in absorbing-state phase transitions.
It is shown that for sufficiently strong disorder the critical behavior is controlled by a strong disorder fixed point and in one dimension the critical exponents are conjectured to be exact: beta=(3-sqrt[5])/2 and nu( perpendicular )=2.


The directed-polymer?directed-percolation transition
We study the relation between the directed polymer and the directed percolation models, for the case of a disordered energy landscape where the energies are taken from bimodal distribution. We find
