Spinning correlators in large-charge CFTs

arXiv:2203.12624 · doi:10.1016/j.nuclphysb.2022.115928

Abstract

We systematically study correlators of a generic conformal field theory with a global O(2) symmetry in a sector of large global charge. We focus in particular on three- and four-point correlators with conserved current insertions sandwiched between spinful excited states corresponding to phonons over the large-charge vacuum. We also discuss loop corrections to the scaling dimensions and observe multiple logarithms in even dimensions.
