Abstract
We study driven interface dynamics in a model with nonlocal shadowing in two spatial dimensions using a nonequilibrium solid-on-solid model. In a wide temperature range, the system forms columnar structures which coarsen with a measured exponent of 0.56±0.02. The power spectrum of the interface shape exhibits a dynamic scaling. At low temperatures the system is described by the Kardar-Parisi-Zhang equation. We discuss the dynamic universality, and present evidence for a nonequilibrium phase transition between a rough and columnar phase.Keywords
