Memory effects in a non-equilibrium growth model

    Research output: Contribution to journalArticlepeer-review


    We study memory effects in a kinetic roughening model. For d=1, a different dynamic scaling is uncovered in the memory dominated phases; the Kardar-Parisi-Zhang scaling is restored in the absence of noise. dc=2 represents the critical dimension where memory is shown to smoothen the roughening front (a=0). 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 t<t, with t being the memory characteristic of the atomistic model. Results can be generalized for other nonconservative systems.
