We find that studying the simplest of the coupled nonequilibrium growth equations of Barabasi by self-consistent 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. 

Symmetries and scaling in generalised coupled conserved Kardar–Parisi–Zhang equations

We study the noisy nonequilibrium dynamics of a conserved density that is driven by a fluctuating surface governed by the conserved Kardar–Parisi–Zhang equation. We uncover the universal scaling

This work investigates the scaling properties of phase transitions between survival and extinction in a model that by itself belongs to the directed percolation (DP) universality class, interacting with a spatiotemporally fluctuating environment having its own nontrivial dynamics.

Dynamics of Spatial Heterogeneity in Landfill - A Stochastic Analysis

A landfill represents a complex and dynamically evolving structure that can be stochastically perturbed by exogenous factors. Both thermodynamic (equilibrium) and time varying (non-steady state)
