标题： Quantum plateaus in dynamical Hall conductivity

摘要： 动态霍尔电导率{\sigma }_H({\omega }) 在垂直磁场中的二维电子气杂质情况被分析。 在低频以及高频下，当兰道能级完全填充时，预测出现平台状行为。 兰道能级的展宽将两个具有不同行为的频率区域分隔开。 动态霍尔电导率的虚部在局域态区域显示出振荡。 进行了与实验的比较。 显示英文摘要

摘要： Dynamical Hall conductivity {\sigma}_H({\omega}) of a 2D electron gas with impurities in the perpendicular magnetic field is analyzed. Plateau-like behavior at low frequencies as well as at high frequencies provided the complete filling of Landau levels is predicted. The broadening of a Landau level separates two frequency regions with different behaviour. Imaginary part of dynamical Hall conductivity reveals oscillations in the localized states region. Comparison with the experiment is carried out.
