Explore advanced concepts in quantum field theory through this conference talk delivered by Dr. Dongsheng Ge from Osaka University at the Isaac Newton Institute. Delve into the construction of interacting conformal line defects within free theories, examining the mathematical frameworks and theoretical approaches that enable such constructions. Learn about the fundamental principles underlying conformal field theory with defects and discover how seemingly non-interacting systems can give rise to complex defect structures. Gain insights into the latest research developments in quantum field theory with boundaries, impurities, and defects, as presented during the specialized BID research programme. Understand the mathematical techniques and physical interpretations that make these theoretical constructions possible, while exploring their implications for broader applications in mathematical physics and quantum field theory.
