Abstract
We have studied numerically the two-probe conductance of a narrow wire in a strong magnetic field using a tight-binding Hamiltonian with random disorder. We found that for a square-well confining potential the interband scattering between edge states is significant and leads to sharp minima in conductance near the transitions from one quantized conductance plateau to another. Within these minima the conductance fluctuates quasiperiodically as a function of the magnetic field.Keywords
