Transdimensional Chern insulators in rhombohedral multilayer graphene superlattices
The study investigates how electron interactions transform a metallic state in twisted rhombohedral graphene into a quantized Chern insulator called a Transdimensional Chern Insulator (TDCI). This new state breaks multiple symmetries and carries unique orbital magnetization. The research uses advanced models to link non-reciprocal motion to this orbital magnetism, suggesting experimental signatures like magnetic hysteresis.
