## Stabilizability and percolation in the infinite volume sandpile model.(English)Zbl 1165.60033

Summary: We study the sandpile model in infinite volume on $$\mathbb Z^d$$. In particular, we are interested in the question whether or not initial configurations, chosen according to a stationary measure $$\mu$$, are $$\mu$$-almost surely stabilizable. We prove that stabilizability does not depend on the particular procedure of stabilization we adopt. In $$d=1$$ and $$\mu$$ a product measure with density $$\rho =1$$ (the known critical value for stabilizability in $$d=1)$$ with a positive density of empty sites, we prove that $$\mu$$ is not stabilizable.
Furthermore, we study, for values of $$\rho$$ such that $$\mu$$ is stabilizable, percolation of toppled sites. We find that for $$\rho >0$$ small enough, there is a subcritical regime where the distribution of a cluster of toppled sites has an exponential tail, as is the case in the subcritical regime for ordinary percolation.
