Chiral Bloch states in rhombohedral n-layer graphene cause high-harmonic generation whose dominant order scales linearly with n, with valley splitting producing n-dependent circular dichroism.
Higher-order k corrections to Dirac dispersion enable Kohn-Luttinger superconductivity, producing topological p-ip pairing in broken-TR systems and anisotropic or warped pairings on TI surfaces.
Leading-order RG analysis shows repulsive interactions stabilize a chiral odd-parity pair density wave in quarter metals of chirally stacked graphene heterostructures.
