Anderson transition in a disordered quasi-one-dimensional system
Prigodin V. N., Firsov Yu. A.
All the states remain localized in the transverse-coupling region w < \/τ4βF when the diagrams with maximally intersecting impurity lines are taken into account in a self-consistent manner. Diffusion occurs at wr £ 1. The frequency dependence of the conductivity is calculated.
