Abstract
We study memory effects in a kinetic roughening model. For , a different dynamic scaling is uncovered in the memory dominated phases; the Kardar-Parisi-Zhang scaling is restored in the absence of noise. represents the critical dimension where memory is shown to smoothen the roughening front . Studies on a discrete atomistic model in the same universality class reconfirm the analytical results in the large time limit, while a different scaling behavior shows up for , with being the memory characteristic of the atomistic model. Results can be generalized for other nonconservative systems.
