Growth and Pattern Formation in the Kardar Parisi Zhang equation — •Hans Fogedby — Department of Physics and Astronomy, Aarhus University, Aarhus, Denmark

A nonperturbative weak noise scheme is applied to the Kardar-Parisi-Zhang equation for a growing interface in all dimensions. It is shown that the growth morphology can be interpreted in terms of a dynamically evolving texture of localized growth modes with superimposed diffusive modes. Applying Derrick's theorem it is conjectured that the upper critical dimension is four.
