A Tensor Network Perspective on Categorical Symmetries and Their Gauging

Explore categorical symmetries and their gauging through the lens of tensor networks in this mathematical physics seminar presented by Bram Vancraeynest-De Cuiper from Universiteit Gent. Delve into advanced concepts at the intersection of quantum field theory, category theory, and tensor network methods as part of the "Quantum field theory with boundaries, impurities, and defects" research programme at the Isaac Newton Institute. Examine how tensor network approaches provide new insights into understanding categorical symmetries, their mathematical structure, and the process of gauging these symmetries in quantum field theoretical contexts. Gain exposure to cutting-edge research methodologies that bridge abstract mathematical concepts with computational techniques used in modern theoretical physics, particularly in the study of quantum systems with various types of boundaries and defects.
