Universality classes and crossover behaviors in non-Abelian directed sandpiles.

摘要: We study universality classes and crossover behaviors in non-Abelian directed sandpile models terms of the metastable pattern analysis. The property induces spatially correlated patterns, characterized by algebraic decay grain density along propagation direction an avalanche. Crossover scaling are observed due to interplay between toppling randomness parity threshold value. In presence such crossovers, we show that broadness distribution plays a crucial role resolving ambiguity class. Finally, claim analysis is important as much conventional avalanche dynamics.
