Non-universal roughening of kinetic self-affine interfaces

Yi-Cheng Zhang
Abstract : Recent experiments of wetting immiscible displacement in porous media and bacteria colony growth are considered as realizations of the Eden interfaces. I propose an explanation of the discrepancy in the scaling behavior between the experiments and the theory. Due to an instability inherent in the growth processes, the presence of unbounded non-Gaussian noise can violate the naive scaling universality.
