SURFACE GROWTH WITH POWER-LAW NOISE IN 2+1 DIMENSIONS

Large scale simulations of stochastic growth of 2 + 1 dimensional surfaces were carried out on a 16K processor Connection Machine. We introduce a family of models for which we could reproduce the known scaling behavior of kinetic roughening in the presence of bounded noise. For noise amplitudes eta distributed according to P(eta) approximately eta-mu-1, the growth exponents depend on mu and they are well described by the recently proposed formula based on the scaling of rare events.
