About
Symmetry has proven to be of fundamental importance for describing Nature. I will discuss recent developments in various generalizations of global symmetries and their applications in quantum field theory, condensed matter physics, and quantum gravity. These generalized global symmetries exist ubiquitously in familiar quantum systems, including the Ising model, Maxwell theory, lattice gauge theories, and Yang-Mills theories. They also feature in more novel topological phases of quantum matter such as fractons. These new symmetries can have generalized anomalies, which lead to nontrivial dynamical consequences on renormalization group flows and analytic constraints on the phase diagram of gauge theories. In the case of fractons and related exotic lattice models in condensed matter theory, the generalized global symmetry results in a surprising UV/IR mixing.
