Metal insulator transition in modulated quantum Hall systems
Mikito Koshino, Tsuneya Ando
The quantum Hall effect is studied numerically in modulated two-dimensional electron systems in the presence of disorder. Based on the scaling property of the Hall conductivity as…

Quantum Hall Effect on the Hofstadter Butterfly
Mikito Koshino, Tsuneya Ando
Motivated by recent experimental attempts to detect the Hofstadter butterfly, we numerically calculate the Hall conductivity in a modulated two-dimensional electron system with dis…
