Avalanches of the Abelian sandpile on the hierarchical lattice
Luca Cattani, Leandro Chiarini, Alessandra Cipriani
Source abstract
We study the Abelian sandpile model on a sequence of finite fractal graphs: the hierarchical, or Migdal--Kadanoff, lattices. Our first main result consists of matching power-law tail bounds for the avalanche and the uniform wave started at certain "pivotal" vertices. We also establish a limiting result for the pivotal reach of the avalanche and, finally, a scaling limit for the size of a uniform wave started at a vertex of high degree.
