Abstract
We examine the effects of correlated perturbations upon globally optim al paths through a random-energy landscape. Motivated by Zhang's early numerical investigations [Phys. Rev. Lett. 59, 2125 (1987)] into grou nd-state instabilities of disordered systems, as well as the work of S hapir [Phys. Rev. Lett. 66, 1473 (199 1)] on random perturbations of r oughened manifolds, we have studied the specific case of random bond i nterfaces unsettled by small random fields, confirming recent predicti ons for the instability exponents. Implications for disordered magnets and growing surfaces are discussed.
