We study the abelian sandpile growth model, where n particles are added at the origin on a stable background configuration in ℤd. Any site with at least 2d particles then topples by sending one particle to each neighbor. We find that with constant background height h≤2d−2, the diameter of the set of sites that topple has order n1/d. This was previously known only for h<d. Our proof uses a strong form of the least action principle for sandpiles, and a novel method of background modification.We…

This paper describes the unexpected finding of an interesting class of backgrounds in two dimensions that show an intermediate behavior: for any N, the avalanches are finite, but the diameter of the pattern increases as N(α), for large N, with 1/2<α≤1.

A sandpile is a cellular automata on a subgraph $\Omega_h$ of ${h}\mathbb Z^2$ which evolves by the toppling rule: if the number of grains at a vertex is at least four, then it sends one grain to

The Abelian sandpile growth model is a diffusion process for configurations of chips placed on vertices of the integer lattice $\mathbb{Z}^d$, in which sites with at least 2d chips {\em topple},

We introduce a new lattice growth model, which we call the boundary sandpile. The model amounts to potential-theoretic redistribution of a given initial mass on ℤd (d ≥ 2) onto the boundary of an (a

We consider patterns generated by adding large numbers of sand grains at a single site in an Abelian sandpile model with a periodic initial configuration, and relaxing. The patterns show

It is shown that driven-dissipative sandpiles continue to evolve even after a constant fraction of the sand has been lost at the sink, and is proved that the density conjecture is false when the underlying graph is any of Z2, the complete graph K(n), the Cayley tree, the ladder graph, the bracelet graph, or the flower graph.

The Abelian sandpile process evolves configurations of chips on the integer lattice by toppling any vertex with at least 4 chips, distributing one of its chips to each of its 4 neighbors. When begun

Abstract We study the rotor router model and two deterministic sandpile models. For the rotor router model in ℤd, Levine and Peres proved that the limiting shape of the growth cluster is a sphere.

It is shown that for high enough densities, a probability measure cannot be stabilized and that in some sense the thermodynamic limit of the uniform measures on the recurrent configurations of the abelian sandpile model is a maximal element of the set of stabilizable measures.

Mathematical aspects of the abelian sandpile model
In 1988, Bak, Tang and Wiesenfeld (BTW) introduced a lattice model of what they called “self-organized criticality”. Since its appearance, this model has been studied intensively, both in the physics
