We study the O(2N) 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.

大电荷膨胀的复苏

我们在大N和大电荷的双比例缩放极限的三个维度上研究了临界状态下的O（2 N）模型。我们证明了大电荷扩张是一个渐近级数，并且我们使用复活技术来研究非微扰校正，并将尾随的有效性扩展到任何电荷值。我们猜想对于任何N值，保形维数的非扰动行为的一般形式，并且发现与先前的晶格数据非常吻合。
