DYNAMICS OF ROUGH SURFACES WITH AN ARBITRARY TOPOLOGY

A model for kinetic growth is presented that allows for overhangs and arbitrary topologies of the growing interface. Numerical studies of the model show that with a choice of the aggregation mechanism equivalent to the one leading to the Kardar-Parisi-Zhang (KPZ) equation [Phys. Rev. Lett. 56, 889 (1986)], we indeed obtain the KPZ results. On changing the aggregation mechanism, different dynamics of the growth are observed
