Abstract

Self-Organized Criticality is the emergence of long-ranged spatio-temporal correlations in non-equilibrium steady states of slowly driven systems without fine tuning of any control parameter. Sandpiles were proposed as prototypical examples of self-organized criticality. However, only some of the laboratory experiments looking for the evidence of criticality in sandpiles have reported a positive outcome. On the other hand a large number of theoretical models have been constructed that do show the existence of such a critical state. We discuss here some of the theoretical models as well as some experiments.
