This article reviews our present knowledge of universality classes in nonequilibrium systems
defined on regular lattices. The first section presents the most important critical exponents …

Non-equilibrium critical phenomena have attracted a lot of research interest in the recent
decades. Similar to equilibrium critical phenomena, the concept of universality remains the …

“The career structure and funding of the universities [...] currently strongly discourages
academics and faculties from putting any investment into teaching–there are no career or …

Universal scaling behavior is an attractive feature in statistical physics because a wide
range of models can be classified purely in terms of their collective behavior due to a …

These lecture notes give a basic introduction to the physics of phase transitions under non-
equilibrium conditions. The notes start with a general introduction to non-equilibrium …

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 …

The pair-contact process with diffusion (PCPD), a generalized model of the ordinary pair-
contact process (PCP) without diffusion, exhibits a continuous absorbing phase transition …

In d> 2 dimensional, homogeneous threshold models discontinuous transition occur, but the
mean-field solution provides 1/t power-law activity decay and other power laws, and thus it is …

Equilibrium phase transitions are associated with rearrangements of minima of a
(Lagrangian) potential. Treatment of nonequilibrium systems requires doubling of degrees of …

The well-established universality classes of absorbing critical phenomena are directed
percolation (DP) and directed Ising (DI) classes. Recently, the pair contact process with …
