Reply to the Comment on `` Moving glass phase of driven lattices ''

Abstract

It was shown in our Letter that the novel glassy property of the moving lattice (transverse critical force and pinned channels) originate {\it only} from the periodicity in the {\it transverse} direction, i.e the underlying smectic density modes of the structure. Thus, contrarily to the claim of the Comment, these properties should be robust to the details of the structure along the direction of motion, even in the presence of a random force (we have demonstrated the existence of a random force in both directions) or dislocations between layers.
