Sandpil model under rotational constraint scaling universality and crossover

Abstract

Sandpile model introduced by Bak Tang and Wiesenfeld BTW was taken as paradigm to study Self Organized Criticality SOC a phenomena of non existence of any characteristic size or time of events in the non equilibrium steady state of a class of slowly driven system The effect of rotational constraint on the toppling dynamics of a sandpile model is studied here constructing a rotational sandpile model RSM RSM has deterministic toppling rule except the first toppling and develops internal
