Ising Meets Ornstein and Zernike, Debye and Huckel, Widom and Rowlinson, and Others
Ronald Dickman
The name Ising has come to stand not only for a specific model, but for an entire universality class - arguably the most important such class - in the theory of critical phenomena.…
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…
First- and second-order phase transitions in a driven lattice gas with nearest-neighbor exclusion
Ronald Dickman
A lattice gas with infinite repulsion between particles separated by lattice spacing, and nearest-neighbor hopping dynamics, is subject to a drive favoring movement along…
Absorbing-state phase transitions in fixed-energy sandpiles
Alessandro Vespignani, Ronald Dickman, Miguel A. Munoz +1
We study sandpile models as closed systems, with conserved energy density playing the role of an external parameter. The critical energy density, , marks a nonequilibrium…
