Derivations of twisted bilayer graphene models
Graphene is made of carbon atoms distributed on a two-dimensional honeycomb network. TBG (twisted bilayer graphene) consists in two layers of graphene stacked on top of each other, and rotated relative to each other. In 2017, a team of experimenters discovered that this system is superconducting, triggering great interest in the condensed matter physics community. The richness of this object comes from its peculiar symmetries and multi-scale character. We will introduce the very recent mathematical literature on the TBG standard model, and then present a new way to derive this type of systems, based on a work done with Éric Cancès and David Gontier
