Ballistic deposition patterns beneath a growing Kardar-Parisi-Zhang interface
Ballistic deposition patterns beneath a growing Kardar-Parisi-Zhang interface
We consider a (1+1)-dimensional ballistic deposition process with next-nearest-neighbor interactions, which belongs to the Kardar-Parisi-Zhang (KPZ) universality class. The focus of our analysis is on the properties of structures appearing in the bulk of a growing aggregate: a forest of independent clusters separated by "crevices." Competition for growth (mutual screening) …
