Nonconservative abelian sandpile model with the bak-tang-wiesenfeld toppling rule
A nonconservative Abelian sandpile model with the Bah-Tang-Wiesenfeld toppling rule introduced by Tsuchiya and Katori [Phys. Rev. E 61, 1183 (2000)] is studied. Using a scaling analysis of the different energy scales involved in the model and numerical simulations it is shown that this model belongs to a universality class different from that of previous models considered in the literature.
