摘要:
We study the sandpile model in infinite volume on 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.
