Abstract
Interfaces subject to random disorder are analyzed by a replica scaling theory. Long-range and short-range disorder corresponds to repulsive and attractive interaction among the replicas, respectively. If these interactions are treated properly, a scaling exponent is given for short-range disorder, such as random bonds; the Flory exponent for long-range disorder, such as random fields, is reproduced.Keywords
