New evidence for super-roughening in crystalline surfaces with disordered substrate

Condensed Matter 2009-10-28 v2 High Energy Physics - Lattice

Abstract

We study the behavior of the Binder cumulant related to long distance correlation functions of the discrete Gaussian model of disordered substrate crystalline surfaces. We exhibit numerical evidence that the non-Gaussian behavior in the low-TT region persists on large length scales, in agreement with the broken phase being super-rough.
