Conductance distributions at the metal-insulator crossover in quasi 1-D pseudorandom wires

A study of the distribution of conductances, P(g), for quasi-one-dimensional (multichain) pseudorandom systems is here presented. We focus on the crossover between the metallic and the insulating regimes with reference to the case of "cosine" and "tangent" pseudorandom potentials. The results are compared with those obtained for the truly random disordered systems with the same geometry. A rich variety of shapes of P(g) is thus evidenced in the crossover-transport regime and, in the case of identical interacting chains composing the device, we have shown that the conductance distribution of the system can be obtained from the results for the single pseudorandom chain.
