Dynamic quantum Hall effect
Lozovik Yu. E. , Farztdinov V. M., Gevorkyan Zh. S.
The Hall response σΗ{ω) of a two-dimensional electron impurity system in a quantizing magnetic field at a frequency ω φ 0 is analyzed. The response σΗ [ω) is predicted to have a dip in its functional dependence on the concentration. The dip results from the filling of localized states and may actually consist of two dips. When the Landau level is completely filled, σΗ (ω) is approximately the same as the response of the pure system.
