Coupled non-equilibrium growth equations: Self-consistent mode coupling using vertex renormalization

Abstract

We find that studying the simplest of the coupled non-equilibrium growth equations of Barabasi by self-consistent mode coupling requires the use of dressed vertices. Using the vertex renormalization, we find a roughness exponent which already in the leading order is quite close to the numerical value.
