Explore the low-energy electrodynamics of quantum anomalous Hall (QAH) states in magnetically doped topological insulators in this 48-minute conference talk. Delve into the phenomenon of dissipationless chiral edge states in quantum Hall effects and their realization without external magnetic fields. Examine the experimental progress in studying Cr-doped (Bi,Sb)2Te3 thin films, which exhibit quantized Hall conductance at temperatures up to 2K. Analyze the unusual frequency dependence observed in terahertz measurements, suggesting strong magnetic gap disorder in the system. Gain insights into the differing effects of this disorder on dc versus ac QAH effects, enhancing understanding of the mathematical aspects of topological insulators.
