Critical exponents in stochastic sandpile models
Alessandro Chessa, Alessandro Vespignani, Stefano Zapperi
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 consis…
Universality in sandpiles
Alessandro Chessa, H. Eugene Stanley, Alessandro Vespignani +1
We perform extensive numerical simulations of different versions of the sandpile model. We find that previous claims about universality classes are unfounded, since the method prev…
Mean-field behavior of the sandpile model below the upper critical dimension
Alessandro Chessa, Enzo Marinari, Alessandro Vespignani +1
We present results of large scale numerical simulations of the Bak, Tang and Wiesenfeld sandpile model. We analyze the critical behavior of the model in Euclidean dimensions $2\leq…
