Attend this mathematical physics seminar exploring the orthogonality catastrophe phenomenon in perturbed conformal field theories, delivered by Professor Anatoly Konechny from Heriot-Watt University at the Isaac Newton Institute. Examine the mathematical foundations and implications of orthogonality catastrophe when conformal field theories undergo perturbations, building on concepts from quantum field theory and statistical mechanics. Delve into the theoretical framework that describes how quantum states become orthogonal under certain perturbative conditions, with particular focus on conformal field theory applications. Explore the mathematical techniques used to analyze these phenomena and their relevance to broader questions in quantum field theory with boundaries, impurities, and defects. Gain insights into current research developments in this specialized area of theoretical physics and mathematics, presented as part of the institute's programme on quantum field theory with boundaries, impurities, and defects.
