Paths to Self-Organized Criticality
Ronald Dickman, Miguel A. Munoz, Alessandro Vespignani +1
We present a pedagogical introduction to self-organized criticality (SOC), unraveling its connections with nonequilibrium phase transitions. There are several paths from a conventi…
Nonuniversality and critical point shift in systems with infinitely many absorbing configurations
Ronald Dickman
A detailed study of critical spreading in the one-dimensional pair contact process is performed using a recently devised reweighting method. The results confirm the validity of a g…
Phase Diagram of the Lattice Restricted Primitive Model
Ronald Dickman, George Stell
We present a comprehensive study of the lattice restricted primitive model, i.e., a lattice gas consisting of an equal number of positively and negatively charged particles interac…
The Pair Contact Process in Two Dimensions
Jafferson Kamphorst Leal da Silva, Ronald Dickman
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…
