论文摘要
最近在大型电荷扩展中计算了带电运算符的缩放尺寸。我们在双重广告模型中验证了这一扩展。具体而言，我们在ADS $ _4 $中的Einstein-Maxwell-Scalar理论的数值构建词素玻色子星形溶液中，发现其大电荷的质量在大型u（1）双电荷扇区中最低算子尺寸的通用形式再现了双电荷的通用形式。
The scaling dimensions of charged operators in conformal field theory were recently computed in a large charge expansion. We verify this expansion in a dual AdS model. Specifically, we numerically construct solitonic boson star solutions of Einstein-Maxwell-Scalar theory in AdS$_4$ and find that its mass at large charge reproduces the universal form of the lowest operator dimension in the large U(1) charge sector of the dual 2+1 dimensional CFT.
