Valley charge-transfer insulator in twisted double bilayer WSe2

Valley charge-transfer insulator in twisted double bilayer WSe2

Abstract In flat-band systems, emergent physics can be substantially modified by the presence of another nearby electronic band. For example, a Mott˘Hubbard insulator can turn into a charge transfer insulator if other electronic states enter between the upper and lower Hubbard bands. Here, we introd...
