In a quiet laboratory, physicists have bent graphene — carbon's most celebrated single-atom sheet — to their will, coaxing two twisted layers into a quantum state that theory long promised but experiment rarely delivered. By rotating one sheet of rhombohedral graphene against another at a precisely controlled angle, researchers have realized a fractional high-Chern insulator, a form of matter where electrons behave according to deep mathematical symmetries rather than ordinary physical intuition. The achievement is significant not only for what it reveals about the hidden architecture of matte
