Abstract
A model of localization based on the Witten Hamiltonian of supersymmet ric quantum mechanics is considered. The case where the superpotential phi(x) is a random telegraph process is solved exactly. Both the loca lization length and the density of states are obtained analytically. A detailed study of the low energy behaviour is presented. Analytical a nd numerical results are presented in the case where the intervals ove r which phi(x) is kept constant are distributed according to a broad d istribution. Various applications of this model are considered. (C) 19 95 Academic Press, Inc.
