HIGHLIGHTS
- who: Si-yu Li from the SchoolUniversity of Sciences, Beijing, China have published the Article: Imaging topological and correlated insulating states in twisted monolayer-bilayer graphene, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
- what: After identifying the electron crystal, the authors focus on its coupling with the intrinsic non-trivial band topology.
SUMMARY
As the bandwidth of those well-isolated flat bands becomes comparable to or less than the Coulomb interaction, the strongly correlated interaction dominates the electronic behavior. In twisted bilayer graphene (tBG), this interaction-driven Mottlike insulators2,5, unconventional . . .
