论文摘要
我们系统地研究了一个通用的保形场理论与全球大电荷扇区中的全球O(2)对称性的相关因素。我们特别关注的是三分和四点相关器,其保守的电流插入夹在与大电荷真空上的声子相对应的跨激发状态之间。我们还讨论了对缩放维度的循环校正,并在均匀的维度上观察多个对数。
We systematically study correlators of a generic conformal field theory with a global O(2) symmetry in a sector of large global charge. We focus in particular on three- and four-point correlators with conserved current insertions sandwiched between spinful excited states corresponding to phonons over the large-charge vacuum. We also discuss loop corrections to the scaling dimensions and observe multiple logarithms in even dimensions.
