Overview

Explore the fascinating world of quantum entanglement and topology in solids through this comprehensive lecture by Harvard University's Ashvin Vishwanath. Delve into the fundamental concepts of quantum superposition, non-locality, and many-particle systems. Discover how entanglement helps classify and uncover new topological phases of matter with potential applications in quantum technologies. Examine the classification of phases, ordered phases, and the role of topology in matter. Investigate specific topics such as integer quantum Hall effect, Chern insulators, 3D Weyl semimetals, and their topological properties. Learn about cutting-edge research in magic angle graphene and correlation effects in twisted bilayer graphene. Gain insights into topology with strong interactions, non-abelian quantum Hall states, and topological order in spin models. Explore the characterization of topological order through entanglement and the remarkable connection between different types of topology in surface topological order. Conclude with a Q&A session to further enhance your understanding of these complex quantum phenomena.
