Explore a 42-minute conference talk on quantum spin liquids and spin-liquid physics in doped t-J models presented by Donna Sheng from California State University, Northridge. Delve into cutting-edge research on strongly correlated gapless quantum many-body systems as part of the "Theories, Experiments and Numerics on Gapless Quantum Many-body Systems" conference at the Kavli Institute for Theoretical Physics. Gain insights into topics such as deconfined quantum critical points, non-Fermi liquids, generalized symmetries, and SYK physics. Discover how this talk contributes to resolving discrepancies in numerical simulations, conformal bootstrap, and theoretical approaches to quantum spin liquids.
