Subclasses in Mixing Correlated Growth Processes with Randomness
arXiv:cond-mat/0511688
Abstract
We show that in the construction of continuum equations for competitive growth processes that are a mixture of random deposition and a correlation process, a distinction must be made within a \textit{single universality class} between depositions that do and do not create voids in the bulk. Within these subclasses the bulk morphology is reflected in the surface roughening via \textit{nonuniversal} prefactors in the universal scaling of the surface width.
