Title: Accessing the CFT spectrum at large charge

Abstract:

Studying strongly coupled CFTs with some global symmetry in sectors
where the associated global charge is large, often leads to an effective
action which is weakly coupled. In this regime, the computation of
anomalous dimensions and fusion coefficients becomes perturbatively
meaningful. I review our recent progress [arXiv:1610.04495, 1612.08985,
1707.00710] in understanding the large-charge sectors of classes of
scalar CFTs in three dimensions, both at the level of the linear as well
as non-linear sigma model. Additionally, I comment on the verification
of the analytic prediction via lattice simulations.
