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 AdS4 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.

大额费用扩张和 AdS/CFT

共形场论中带电算子的标度维度最近在一个大的电荷扩展中被计算出来。我们在双 AdS 模型中验证了这种扩展。具体来说，我们在 AdS4 中数值构建了爱因斯坦-麦克斯韦-标量理论的孤子玻色子星解，并发现其大电荷质量再现了双 2+1 的大 U(1) 电荷扇区中最低算子维数的通用形式。立体 CFT。
