标题： NLO in the large charge sector of the critical $O(N)$ model at large $N$

摘要： 我们计算了在双尺度极限下，大荷值算符在$3d$临界$O(N)$模型中的次次领头阶修正，其中同时取$N$和算符荷值$Q$为大值。 当$Q \gg N$时，我们的结果与共形超流有效场论的预测相匹配，并允许提取有效场论威尔逊系数的次次领头阶修正。 目前，我们的结果代表了弱耦合共形场论中大荷值算符标度维数的最精确确定。 显示英文摘要

摘要： We compute the next-to-leading correction to the scaling dimension of large-charge operators in the $3d$ critical $O(N)$ model in a double scaling limit in which both $N$ and the operator charge $Q$ are taken to be large. When $Q \gg N$ our result matches predictions from the conformal superfluid EFT and allows to extract next-to-leading order corrections to the EFT Wilsonian coefficients. At present, our result represents the most precise determination of large-charge operator scaling dimension in weakly-coupled CFTs.
