Electric Field Tunable Band Gap in Commensurate Twisted Bilayer Graphene
Spenser Talkington, Eugene J. Mele
Bernal bilayer graphene exhibits a band gap that is tunable through the infrared with an electric field. We show that sublattice odd commensurate twisted bilayer graphene (C-TBG) e…

Terahertz Circular Dichroism in Commensurate Twisted Bilayer Graphene
Spenser Talkington, Eugene J. Mele
We report calculations of terahertz ellipticities in large-angle, 21.79 and 38.21, commensurate twisted bilayer graphene, and predict values as high as 1.5 millideg…
