| Abstract: | The effect of a continuous model of correlations upon
one-dimensional finite disordered quantum wires modeled by an array of
delta-potentials, is analyzed. Although the model proposed is not able to
include new truly extended states in the spectrum, the transport properties
of a finite sample are noticeably improved due to the existence of states
whose localization length is larger than the system size. This
enhancement of transmission is maximized for relatively short chains. |
