Introduction to the large charge expansion

Abstract: Working in sectors of large global charge leads to important simplifications when studying strongly coupled CFTs. In this talk I will introduce the large-charge expansion via the simple example of the O(2) model and apply it in a number of other situations displaying a richer structure, such as non-Abelian vector models, supersymmetric N=2 systems and asymptotically safe theories.
