对称积CFT_2的自旋链

A Spin Chain for the Symmetric Product CFT_2

Ari Pakman, Leonardo Rastelli, Shlomo S. Razamat

摘要:

我们考虑Sym^N T^4中的“规范不变”算子,Sym ^N T^4是具有T^4目标的二维超对称西格玛模型的N个拷贝的对称乘积轨道。本文讨论了单圈算子的自旋链表示,并研究了它们在N大时的两点函数。我们进行系统的计算,在轨道点(“树级”),其中非平凡的混合已经存在,和一些样本计算的一阶吹胀模式的轨道(“一个循环”)。

英文摘要:

We consider "gauge invariant" operators in Sym^N T^4, the symmetric product orbifold of N copies of the 2d supersymmetric sigma model with T^4 target. We discuss a spin chain representation for single-cycle operators and study their two point functions at large N. We perform systematic calculations at the orbifold point ("tree level"), where non-trivial mixing is already present, and some sample calculations to first order in the blow-up mode of the orbifold ("one loop").
