Abstract
Scattering between edge states that bound one-dimensional domains of o pposite potential or flux is studied, in the presence of strong potent ial or flux disorder. A mobility edge is found as a function of disord er and energy, and we have characterized the extended regime. In the p resence of flux and/or potential disorder, the localization length sca les exponentially with the width of the barrier. We discuss implicatio ns for the random-flux problem.
