Experimental discovery of a family of high-Chern-number orbital magnets in twisted (1+n) rhombohedral graphene with observed topological hierarchy C = n for n=3,4,5.
Displacement fields in rhombohedral pentalayer graphene cause asymmetric flattening of conduction versus valence bands, producing near-ideal quantum geometry that supports fractional quantum anomalous Hall states under electron doping.
Leading-order RG analysis shows repulsive interactions stabilize a chiral odd-parity pair density wave in quarter metals of chirally stacked graphene heterostructures.
