Explore a 46-minute conference talk on numerical studies of critical behavior in systems with boundaries and defects. Delve into cutting-edge research presented by Francesco Parisen Toldin from RWTH Aachen at the Kavli Institute for Theoretical Physics. Gain insights into the latest developments in gapless quantum many-body systems, including deconfined quantum critical points, quantum spin liquids, and non-Fermi liquids. Discover how this talk contributes to resolving discrepancies between numerical simulations, conformal bootstrap, and theoretical approaches. Learn about new perspectives on compressible quantum liquids, generalized symmetries, and emergent phenomena in gapless states. Understand the implications of duality on quantum critical points and explore recent experimental progress in strongly correlated gapless states. Recorded as part of the "Theories, Experiments and Numerics on Gapless Quantum Many-body Systems" conference, this presentation offers a unique opportunity to engage with frontier research in condensed matter physics and quantum many-body systems.
