This talk describes a general methodology for the multiscale analysis of atomistic models of fluctuating interfaces. Beginning with an exact analytic formulation of kinetic Monte Carlo simulations in the form of a lattice Langevin equation, we derive stochastic partial differential equations for the smoothed lattice models by regularizing the transition rules. Subsequent coarse-graining is accomplished by calculating renormalization-group (RG) trajectories from initial conditions determined by the regularized atomistic models. The same methods can be applied in wider settings, including the Burgers’ equation for fluids and spinodal decomposition, as described by the Cahn-Hilliard equation.
