Tunable fractional Chern insulators

Rhombohedral hexalayer graphene aligned with hexagonal boron nitride has joined the growing family of systems capable of hosting fractional Chern insulators. Its fractional Chern insulator state at filling factor ν = 2/3 is tunable via both an electric displacement field and magnetic field, revealing rich topological phase transitions and intriguing details in the topological order.
