Resurgence of the large-charge expansion
Nicola Andrea Dondi, Ioannis Kalogerakis, Domenico Orlando, Susanne Reffert
Abstract
A bstract We study the O(2 N ) model at criticality in three dimensions in the double scaling limit of large N and large charge. We show that the large-charge expansion is an asymptotic series, and we use resurgence techniques to study the non-perturbative corrections and to extend the validity of the eft to any value of the charge. We conjecture the general form of the non-perturbative behavior of the conformal dimensions for any value of N and find very good agreement with previous lattice data.
