Numerical simulation of the Kardar-Parisi-Zhang equation

Abstract
We simulate the Kardar-Parisi-Zhang equation [Phys. Rev. Lett. 56, 889 (1986)] in 2+1 dimensions. It is a nonlinear stochastic differential equation that describes driven growing interfaces. The Hopf-Cole transformation is used in order to obtain a stable numerical scheme. The two relevant critical exponents are precisely measured.
