The quantum localization is known to be responsible for the deep conductivity minima of the quantum Hall e ect. In this paper we calculate the localization length as a function of magnetic ΓΏeld B at such minima for several models of disorder ("white-noise", short-range, and long-range random potenti
We discuss the microscopic mechanism for the onset of dissipation in a quantum Hall system. Based on general results on the time dependence of the states in a disorder-broadened Landau band in the presence of a macroscopic electric field E, it is found that the mobility edges move from the band cent
