Entanglement in Quantum Solids and the Second Quantum Revolution

Wednesday, March 20, 2019 - 11:00am

Quantum entanglement is the origin of both the weirdness associated with   quantum systems and the power of many proposed quantum technologies. While largely studied in the the context of a few particles, recent work has emphasized its importance in  macroscopic systems, such as electronic solids with many interacting particles. I will discuss  examples where quantum entanglement has helped us classify and discover new topological phases of matter, which may have applications to future quantum devices. Finally, I will review related theoretical progress on a remarkable new quantum system -  two sheets of graphene, rotated relative to one another by just one degree -  where a variety of states including superconductivity have been observed.
