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

摘要: A study of the distribution conductances, P(g), for quasi-one-dimensional (multichain) pseudorandom systems is here presented. We focus on crossover between metallic (\(\langle g \rangle \gtrsim 1\)) and insulating (〈g〉∼0) regimes with reference to case “cosine” “tangent” potentials. The results are compared those obtained truly random disordered same geometry. rich variety shapes P(g) thus evidenced in crossover-transport regime and, identical interacting chains composing device, we have shown that conductance system can be from single chain.
