Explore a defect-based geometrisation approach to generalised symmetries in three-dimensional quantum field theory in this seminar lecture delivered by Dr. Andrea Ferrari from Deutsches Elektronen-Synchrotron. Delve into advanced theoretical physics concepts as the speaker presents research on how defects can be used to geometrically understand generalised symmetries within the framework of three-dimensional systems. Learn about the mathematical structures and physical principles underlying this approach, examining how defect configurations relate to symmetry properties in quantum field theories. Discover the implications of this geometrisation method for understanding boundary conditions, impurities, and defects in quantum field theory systems. Gain insights into cutting-edge research at the intersection of mathematical physics, quantum field theory, and symmetry analysis. This presentation forms part of the "Quantum field theory with boundaries, impurities, and defects" research programme at the Isaac Newton Institute for Mathematical Sciences, offering an opportunity to engage with contemporary developments in theoretical physics and their mathematical foundations.
