Explore the orthogonality catastrophe phenomenon in perturbed conformal field theories through this seminar lecture delivered by Professor Anatoly Konechny from Heriot-Watt University. Delve into the mathematical and physical implications of orthogonality catastrophe when conformal field theories undergo perturbations, examining how this fundamental quantum field theory concept manifests in systems with boundaries, impurities, and defects. Gain insights into advanced theoretical physics concepts as part of the broader program on quantum field theory with boundaries, impurities, and defects, presented at the Isaac Newton Institute.
