Self-organized growth model for a driven interface in random media.
We introduce a simple self-organized growth model in the quenched Edwards-Wilkinson universality class. The roughness and growth exponents are obtained for the model as alpha approximately 1.15 and beta approximately 0.89, respectively. These values of exponents are in good agreement with previous results obtained from numerical integrations or discretized model simulations of the quenched Edwards-Wilkinson equation. The velocity of a driven interface is found to be independent of the slope of the tilted substrate.
