Untying the insulating and superconducting orders in magic-angle graphene
The coexistence of superconducting and correlated insulating states in magic-angle twisted bilayer graphene prompts fascinating questions about their relationship. Independent control of the microscopic mechanisms that govern these phases could help uncover their individual roles and shed light on their intricate interplay. In this study, scientists report on direct tuning of electronic interactions in this system by changing the separation distance between the graphene and a metallic screening layer.
