Disorder driven collapse of the mobility gap and transition to an insulator in fractional quantum Hall effect
D. N. Sheng, Xin Wan, E. H. Rezayi +3
We study the nu=1/3 quantum Hall state in presence of the random disorder. We calculate the topologically invariant Chern number, which is the only quantity known at present to una…

Exact diagonalization study of domain structure in integer filling factor quantum Hall ferromagnets
E. H. Rezayi, T. Jungwirth, A. H. MacDonald +1
Opposite spin Landau levels in a quantum well can be brought into coincidence by tilting the magnetic field away from normal orientation. We demonstrate that the magnetotransport a…
