On the existence of an upper critical dimension for systems within the KPZ universality class
Published 21 Feb 2015 in cond-mat.stat-mech | (1502.06121v1)
Abstract: In this work we extend the etching model to $d+1$ dimensions. This permits us to investigate its exponents behaviour on higher dimensions, to try to verify the existence of an upper critical dimension for the KPZ equations, with our results sugesting that $d=4$ is not an upper critical dimension for the etching model.
