Higher Berry Phases, Tensor Networks, and Boundary Conformal Field Theory

Explore advanced concepts in quantum field theory through this seminar lecture delivered by Professor Shinsei Ryu from Princeton University at the Isaac Newton Institute. Delve into the intricate connections between higher Berry phases, tensor networks, and boundary conformal field theory as part of the "Quantum field theory with boundaries, impurities, and defects" research programme. Examine how these mathematical frameworks intersect to provide deeper insights into quantum systems with boundaries and topological properties. Learn about the theoretical foundations and applications of Berry phases in higher-dimensional contexts, understand the role of tensor networks in describing quantum many-body systems, and discover how boundary conformal field theory provides powerful tools for analyzing critical phenomena at interfaces. Gain exposure to cutting-edge research methodologies that bridge condensed matter physics, quantum information theory, and mathematical physics, presented by a leading expert in the field of theoretical condensed matter physics and quantum many-body systems.
