Microscopic theory of quantum anomalous Hall effect in graphene
We present a microscopic theory to give a physical picture of the formation of the quantum anomalous Hall (QAH) effect in magnetized graphene coupled with Rashba spin-orbit coupling. Based on a continuum model at valley $K$ or ${K}^{\ensuremath{'}}$, we show that there exist two distinct physical origins of the QAH …
