Superconducting Mechanism and Order Parameter in Twisted Bilayer Graphene - From the Heavy Fermion Model

Explore a 42-minute conference talk by Andrei Bernevig from Princeton University on the superconducting mechanism and order parameter in twisted bilayer graphene (TBG) from the perspective of the Heavy Fermion Model. Delivered as part of the "Moiré materials: A New Paradigm in Tunable Quantum Matter" conference at the Kavli Institute for Theoretical Physics (KITP), this presentation delves into pressing theoretical questions surrounding moiré materials. Gain insights into the origin of superconductivity, the nature of correlated states, and the role of topology in these highly tunable quantum systems. Learn about the unprecedented level of band structure, symmetry, and topology tunability offered by moiré materials, and how they serve as a rich platform for investigating various phenomena within a unified approach. Discover emerging tunable platforms, including twisted superconductors, topological surface states, quasi-periodic moiré systems, and twisted magnetic materials. Recorded on August 20-23, 2024, in Santa Barbara, CA, this talk is part of a broader conference exploring experimental challenges, novel techniques, and theoretical advancements in the field of moiré materials.
