摘要：

Sandpile model is studied here imposing rotational constraint on the flow of sand grains. The rotational constraint is constituted by certain deterministic rules. The rotational dynamics evolves the system into a non-equilibrium steady state characterized by power law correlations and exhibits self organized criticality. The exponents characterizing the power law distributions of avalanche properties are found different from other models. Consequently the present model belongs to a new universality class.
