Abstract

We show that the correlator of three large charge operators with minimal scaling dimension can be computed semiclassically in CFTs with a U(1)U(1) symmetry for arbitrary fixed values of the ratios of their charges. We obtain explicitly the OPE coefficient from the numerical solution of a nonlinear boundary value problem in the conformal superfluid EFT in 3d3d. The result applies in all three-dimensional CFTs with a U(1)U(1) symmetry whose large charge sector is a superfluid.
