Electrical band flattening, valley flux, and superconductivity in twisted trilayer graphene
Alejandro Lopez-Bezanilla, J. L. Lado
Abstract
The paper shows that an interlayer bias allows controlling flat bands and creating internal valley currents in twisted trilayer graphene. The authors also show that the introduction of interactions leads to the the emergence of a nonuniform superconducting state that impacts high energy bands
