Transport properties of double quantum wires with correlated disorder

The Anderson localization of electrons in disordered tunnel-coupled double quantum wires (DQW) in a perpendicular magnetic field is studied. The localization length is calculated for the disorder with short-range spatial correlations, either within each wire or between the two wires of the DQW. It is shown that the interwire correlations produce a remarkably strong effect on the localization length at energies inside the partial energy gap of the DQW. The implications of obtained results for the transport properties of DQWs with disorder due to boundary roughness are discussed.
