  In a previous paper (Eur. Phys. J. B 30, 239-251 (2002)) we have presented
the main features and properties of a simple model which -in spite of its
simplicity- describes quite accurately the qualitative behaviour of a quantum
wire. The model was composed of N distinct deltas each one carrying a different
coupling. We were able to diagonalize the Hamiltonian in the periodic case and
yield a complete and analytic description of the subsequent band structure.
Furthermore the random case was also analyzed and we were able to describe
Anderson localization and fractal structure of the conductance. In the present
paper we go one step further and show how to introduce correlations among the
sites of the wire. The presence of a correlated disorder manifests itself by
altering the distribution of states and the localization of the electrons
within the system
