Unveiling the chirality of the quantum anomalous Hall effect
Published 2024“…The quantized lδz will also give rise to a unique quantized magnetic circular dichroism effect in the case of resonance absorption. By lδz, we find that the chiral flow-direction of an electron in the QAHE is not explicitly related to the intrinsic spin axis, thereby enabling the spin-momentum-unlocking edge states in an antiferromagnetic QAHE system. …”
