Effects of disorder on modulated quantum Hall systems

M. Koshino, T. Ando

Research output: Contribution to journalArticlepeer-review


The Hall conductivity and the localization length are calculated for weakly modulated two-dimensional systems within the lowest Landau level approximation. We find that the fractal character of the Hofstadter butterfly is reflected on the coincidence in the localization and the Hall conductivity among a series of fluxes φ + 2 n with integers n.
