Non-Invertible SPTs - An On-Site Realization of (1+1)d Anomaly-Free Fusion Category Symmetry

Watch this seminar from the Isaac Newton Institute exploring the on-site realization of (1+1)d anomaly-free fusion category symmetry through non-invertible symmetry-protected topological phases. Learn about advanced concepts in quantum field theory as Ms Xinping Yang from Yale University presents her research on non-invertible SPTs and their mathematical foundations. Discover how these theoretical frameworks contribute to understanding quantum systems with boundaries, impurities, and defects. Gain insights into the intersection of topology, symmetry, and quantum field theory through detailed mathematical analysis and theoretical developments. Explore the implications of anomaly-free fusion categories in low-dimensional quantum systems and their role in modern theoretical physics. This presentation is part of the "Quantum field theory with boundaries, impurities, and defects" research programme at the Isaac Newton Institute for Mathematical Sciences.
