Abstract
The paper proposes a new electronic mechanism for the observation of unconventional superconductivity observed in twisted bilayer graphene. Using the Migdal-Eliashberg framework, the authors show that collective excitations, such as plasmons, can mediate superconductivity in this system, and also reproduce some experimental features.
