Emergent Phenomena in Crystalline Multilayer Graphene

Explore emergent quantum phenomena in crystalline multilayer graphene during this physics colloquium talk. Delve into the world of condensed matter physics, focusing on electron correlation and topology in conventional crystalline materials with flat electronic bands. Discover how moiré superlattices built on 2D materials have become a new platform for studying these phenomena. Learn about a family of synthetic quantum materials based on crystalline multilayer graphene, which combines flat-bands in highly ordered conventional crystalline materials with proximity effects enabled by 2D van der Waals heterostructures. Examine the rich spectrum of emergent phenomena observed in experiments, including correlated insulators, spin/valley-polarized metals, integer and fractional quantum anomalous Hall effects, and superconductivities. Consider the implications of these findings for topological quantum computation and gain insights into cutting-edge research in the field of physics.
