✦ Synopsis

The two-terminal conductance of quantum Hall wires in the presence of spatially correlated disorder is investigated numerically. It is found that the conductance plateau transitions shift to higher energies than the corresponding Landau subband centers. By performing the analysis on individual samples, it is found that the critical energy of the plateau transition depends on the disorder realization, but the distance between successive critical energies is independent of the sample and is equal to the bulk Landau level separation.
