Critical exponents in stochastic sandpile models
Alessandro Chessa, Alessandro Vespignani, Stefano Zapperi
Abstract
We present large scale simulations of a stochastic sandpile model in two dimensions. We use moments analysis to evaluate critical exponents and finite size scaling method to consistently test the obtained results. The general picture resulting from our analysis allows us to characterize the large scale behavior of the present model with great accuracy.
