Hf. Chau et C. Ho, EFFECTS OF THE RELATIVE SCALES BETWEEN PARTICLES ADDED AND TOPPLED EACH TIME ON THE DISTRIBUTION OF AVALANCHE SIZE IN ABELIAN SANDPILES, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 49(1), 1994, pp. 902-905
We study the distribution function of avalanche size, P-x(s), for a ge
neral Abelian sandpile as a function of the number of particles x adde
d each time. An exact piecewise Linear relation between various P-x is
derived provided that the particles are added to one and only one sit
e each time. This is then verified by numerical simulation. We find th
at P-x(s) depends, but maybe not very strongly in general, on x. Thus
x can be regarded as a fine-tune parameter for the Abelian sandpiles.
