Twisted bilayer graphene paper published in Nature Physics

Our work shows that under finely tuned conditions, and contrary to theoretical expectations, it is possible to achieve an anomalous Hall effect at half filling of the flat bands in twisted bilayer graphene. This work may help to unravel the nature of the competing correlated grounds states at half filling, and their connection to superconductivity. Congratulations to Chun-Chih, Xuetao, and Zhaoyu!
