Title: Resurgence of the large-charge expansion

Abstract: In this talk I will discuss the d=3 Wilson-Fisher O(N) CFT in a large-charge sector, where also N is taken to be large. The large-charge expansion of critical exponents of the model turns out to be an asymptotic series with double factorial growth. Resurgent …

Title: Untangling scaling dimensions of fixed charge operators in a CFT

Abstract: I will start with a brief pedagogic review of the semiclassical method for determining the scaling dimensions of fixed-charge operators in conformal field theory (CFT) with global symmetries and then introduce a general strategy to …
