Non-uniform Berry curvature in parent Chern bands induces momentum-space vortices in the chiral superconducting gap function, with the parent Chern number constraining vortex count independently of model details.
Direct magnetometry imaging establishes reconfigurable chiral superconductivity in rhombohedral graphene with low-current domain control.
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.
