摘要

We have characterized the dynamics of a rough interface analytically and numerically. From a time-dependent Ginzburg-Landau equation with quenched disorder in the mobility we have obtained a macroscopic model with disorder. The corresponding in-terfacial equation in Fourier space has given rise to a new universality class with a crossover from short to long times that are corroborated by our numerical results. We are indebted to J. Soriano and J. Ortin for valuable discussions in all the stages of the present work. We acknowledge financial support from Direction General de Investigation Cientifica y Tecnica (Spain) under projects BFM2000-0628-C03 and BFM2000-0624-C03-02.
