Coupled nonequilibrium growth equations: Selfconsistent mode coupling using vertex renormalization
Abstract
We find that studying the simplest of the coupled nonequilibrium growth equations of Barabasi by selfconsistent mode coupling requires the use of dressed vertices. Using the vertex renormalization, we find a roughening exponent which already in the leading order is quite close to the numerical value.
