Sandpiles and absorbing-state phase transitions: recent results and open problems
Miguel A. Munoz, Ronald Dickman, Romualdo Pastor-Satorras +2
We review some recent results on the relations between sandpiles and a class of absorbing state phase transitions. We use the concept of fixed energy sandpiles (FES), in which exte…
Lattice on Lattice in Two Dimensions
Ronald Dickman, Eugene M. Chudnovsky
We study a harmonic triangular lattice, which relaxes in the presence of a weak, short-wavelength periodic potential. Monte Carlo simulations reveal that the elastic lattice has on…
Generalized Scaling for Models with Multiple Absorbing States
J. F. F. Mendes, Ronald Dickman, Malte Henkel +1
At a continuous transition into a nonunique absorbing state, particle systems may exhibit nonuniversal critical behavior, in apparent violation of hyperscaling. We propose a genera…
