Superconductivity and quantized anomalous Hall effect in rhombohedral graphene.

Inducing superconducting correlations in chiral edge states is predicted to generate topologically protected zero energy modes with exotic quantum statistics. Experimental efforts so far have focused on engineering interfaces between superconducting materials-typically amorphous metals-and semiconducting quantum Hall or quantum anomalous Hall systems. However, the strong interfacial disorder inherent in this approach can prevent the formation of isolated topological modes.
