Kerr and Faraday rotations in topological flat and dispersive band structures

Integer quantum Hall (IQH) states and quantum anomalous Hall (QAH) states show the same static dc response but distinct dynamical ac response. In particular, the ac anomalous Hall conductivity profile σ _yx ( ω ) is sensitive to the band shape of QAH states. For example, dispersive QAH bands shows r...
