AI总结:

本文研究了具有纯通用NSNS通量的${\rm AdS}_3\times X$背景下弦的DDF算子,构造了对应时空线性膨胀子场的DDF算子,为对偶CFT猜想提供了证据,并暗示了通用$X$下$\mathbb{R}_{\widetilde{Q}}$的存在性。

摘要:

我们研究了在具有纯且\textit{通用}的NSNS通量的${\rm AdS}_3\times X$背景下,玻色弦和超弦的谱生成算子(DDF算子)。猜想其对偶CFT是$\mathbb{R}_{\widetilde{Q}}\times X$的变形对称轨道,其中$\mathbb{R}_{\widetilde{Q}}$表示斜率为$\widetilde{Q}$的线性膨胀子理论。本文在世界片理论变为自由的极限下,构造了对应于时空线性膨胀子场的DDF算子。该DDF算子为所提出的对偶CFT提供了另一项证据。此外,该DDF算子纯粹由$\rm AdS_3$场构造而成,从而强烈暗示了对于定义一致背景的通用$X$,$\mathbb{R}_{\widetilde{Q}}$的存在性。

英文摘要:

We study the spectrum generating operators (DDF operators) for bosonic strings and superstrings in ${\rm AdS}_3\times X$ with pure, $\textit{generic}$ NSNS flux. The dual CFT is conjectured to be a deformed symmetric orbifold of $\mathbb{R}_{\widetilde{Q}}\times X$, where $\mathbb{R}_{\widetilde{Q}}$ denotes a linear dilaton theory with slope $\widetilde{Q}$. In this paper, we construct DDF operators corresponding to the spacetime linear dilaton field in the limit where the worldsheet theory becomes free. The DDF operator gives another evidence supporting the proposed dual CFT. Furthermore, the DDF operator is constructed purely from the $\rm AdS_3$ fields and thus, strongly implies the existence of $\mathbb{R}_{\widetilde{Q}}$ for generic $X$ that defines a consistent background.
