Effect of Coulomb impurities on the electronic structure of magic angle twisted bilayer graphene
Abstract In graphene, charged defects break the electron-hole symmetry and can even give rise to exotic collapse states when the defect charge exceeds a critical value which is proportional to the Fermi velocity. In this work, we investigate the electronic properties of twisted bilayer graphene (tBL...
