Kavli Affiliate: Jing Wang | First 5 Authors: Jinjiang Zhu, Yang Feng, Xiaodong Zhou, Yongchao Wang, Zichen Lian | Summary: The chiral edge current is the boundary manifestation of the Chern number of a quantum anomalous Hall (QAH) insulator. Its direct observation is assumed to require well-quantized Hall conductance, and is so far lacking. The […]
