New symmetry-broken Chern insulators with C = +3, ±2, ±1 at v = -2.5 or -2.6, plus the known C = -4 at v = -1, were observed in rhombohedral tetralayer graphene/hBN moiré superlattices and shown to be tunable via twist angle, electric field, and magnetic field.

An operator contraction method with three fundamental rules exactly decomposes Laughlin and Halperin fractional quantum Hall states, allowing orbital entanglement spectra computations up to 16 particles that match chiral Luttinger liquid theory.
Lattice models with engineered quantum geometry host Abelian and non-Abelian fractional Chern insulators, anomalous Hall crystals, and Halperin states, with the N=2 model realizable in twisted MoTe₂.
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.
