  • Trilayer graphene with the layers consecutively twisted by the same angle is shown to be a platform in which correlated and topological states exist, driven by local lattice relaxations.

  • Aligning magic-angle twisted bilayer graphene to boron nitride layers introduces a gate hysteresis coexisting with its strongly correlated phases. This bistability enables electrical switching between superconducting, metallic and insulating states.

  • Superconductivity is reported in magic-angle twisted four-layer and five-layer graphene systems. While they find that all magic-angle graphene systems fit into a unified hierarchy of systems that share a set of flat bands in their electronic band structures, they also report that there is a key distinction between magic-angle twisted bilayer graphene and the other family members, related to the difference in the way the electrons move between the layers in a magnetic field.
