Regarding Nicola's suggestion to map onto a tight binding Hamiltonian as a
starting point relevant parameters derived from a QE calculation and then
randomize for a subsequent quantum Monte Carlo estimate of Anderson
localization, have a look at the this paper
%5b(TMTSF)_2X%5d.pdf .

I guess you could map the problem into a tight-binding hamiltonian, decide
how disorder influences that, and diagonalize?
