Stirred Kardar-Parisi-Zhang equation with quenched random noise: Emergence of induced nonlinearity

P. I. Kakin, M. A. Reiter, M. M. Tumakova +2

We study the stochastic Kardar-Parisi-Zhang equation for kinetic roughening where the time-independent (columnar or spatially quenched) Gaussian random noise $f(t,\mathbf{x})$ is spec…
