Abstract
A scattering formalism is developed for a random potential on a cylinder with flux along its axis. Simulations show the possibility of a phase transition in the dependence of an ensemble-averaged conductance: The periodicity in changes from h/2e to h/e as the potential is weakened. The critical potential decreases as the sample size increases such that the zero-flux conductivity is 1/4150e2/h.
