In systems with multiple energy bands, the interplay between electrons with different effective masses drives correlated phenomena that do not occur in single-band systems. Magic-angle twisted trilayer graphene is a tunable platform for exploring such effects, hosting both heavy (“bound”) electrons and light (“weakly bound and mobile”) electrons.
Researchers at Harvard, MIT and National Institute for Material Science in Japan have examined the interplay between “light” and “heavy” electrons in magic-angle twisted trilayer graphene, shedding new light on how they may help form novel quantum states.
