Attractive electron-electron interactions from internal screening in magic angle twisted bilayer graphene

22 Nov 2019 Goodwin Zachary A. H. Corsetti Fabiano Mostofi Arash A. Lischner Johannes

Twisted bilayer graphene (tBLG) has recently emerged as a new platform for studying electron correlations, the strength of which can be controlled via the twist angle. Here, we study the effect of internal screening on electron-electron interactions in undoped tBLG... (read more)
