Self-duality properties, localization centers, and magnetic energy of the electronic wave functions at small magic angles in twisted bilayer graphene

Interfacial magnon-mediated superconductivity in twisted bilayer graphene

“…The relative twist angle of the two graphene layers creates a long-period moiré pattern that, in turn, gives rise to flat electronic bands at certain magic angles [18][19][20]. At higher-order magic angles, the flat bands can be related to the quantum Hall effect [21,22]. Flat bands at the magic angles greatly enhance the electron DOS.…”
