We show that in the one-dimensional (1D) Anderson model long-range
correlations within the sequence of on-site potentials may lead to a region of
extended states in the vicinity of the band centre, i.e., to a
correlation-induced insulator-metal transition. Thus, although still
disordered, the 1D system can behave as a conductor.
