Correlation-driven topological phases in magic-angle twisted bilayer graphene

Nature, Published online: 18 January 2021; doi:10.1038/s41586-020-03159-7

Correlation-driven topological phases with different Chern numbers are observed in magic-angle twisted bilayer graphene in modest magnetic fields, indicating that strong electronic interactions can lead to topologically non-trivial phases.
