The Abelian Sandpile Model is a cellular automaton whose discrete dynamics reaches an out-of-equilibrium steady state resembling avalanches in piles of sand. This system shows, in an apparently unpredictable way, bursts of activity such as avalanches. This kind of model can be eventually driven into an out-of-equilibrium steady state. We propose a numerical study of the “recurrent configurations”, i.e. a set of patterns recreated periodically after each avalanche.
