Quantum Anomalous Hall Effect with Higher Plateaus
Quantum Anomalous Hall Effect with Higher Plateaus
Quantum anomalous Hall (QAH) effect in magnetic topological insulators is driven by the combination of spontaneous magnetic moments and spin-orbit coupling. Its recent experimental discovery raises the question if higher plateaus can also be realized. Here we present a general theory for QAH effect with higher Chern numbers, and show …
