Title
Magic Angle Graphene: A New Platform for Strongly Correlated Physics
Abstract
The understanding of strongly-correlated quantum matter has challenged physicists for decades. Such difficulties have stimulated new research paradigms, such as ultra-cold atom lattices for simulating quantum materials. In this talk I will present a new platform to investigate strongly correlated physics, based on graphene moiré superlattices. In particular, I will show that when two graphene sheets are twisted by an angle close to the ‘magic angle’, the resulting flat electronic structure gives rise to a rich and highly tunable phase diagram exhibiting unusual correlated insulator states and superconductivity.
