摘要: We introduce and study a new directed sandpile model with threshold dynamics stochastic toppling rules. show that particle conservation law the percolation-like local evolution of avalanches lead to formation spatial structure in steady state, density developing power tail away from top. determine scaling exponents characterizing avalanche distributions terms critical percolation all dimensions.
