Abstract: B72.00001 : Graphene-Based Moire Superconductors: Platform for New Discoveries and Applications*
11:30 AM–12:06 PM
Twisted bilayer graphene can host an abundance of correlated insulating, topological, and superconducting
states of matter. While many recent results strongly point towards the unconventional nature of the
superconductivity in this material, the precise pairing mechanism and superconducting order remain elusive.
This talk will first discuss our current understanding of electronic properties in this and the related
broader family of graphene-based moire superconductors obtained by transport and local scanning tunneling
microscopy measurements. In particular, I will present results on how the additional layers can improve
the tunability of the superconducting phase and its overall robustness. In the second part, I will discuss how
we might use this novel highly tunable materials platform for quantum science applications.
