Engineering Correlation and Topology in Two-Dimensional Moire Superlattices

 · Invited

Abstract

Van der Waals heterostructures of atomically thin crystals offer an exciting new platform to design novel electronic and optical properties. In this talk, I will describe how to engineer correlated and topological physics using moire superlattice in two dimensional heterostructures. I will show that we can realize and control extremely rich condensed matter physics, ranging from correlated Mott insulator and superconductivity to ferromagnetism and topological Chern insulator, in a single device featuring the ABC trilayer graphene and boron nitride moire superlattices.
