论文摘要
我们在带电的旋转黑人背景中构建了一种新颖的时间般的coset sigma模型，描述了II型超弦理论，该理论在IR中的本地$ ADS_3 $之间与紫外线中的线性 - 迪拉顿几何形状进行了插值。这允许人们在非ADS背景中对全息图进行系统研究，并平稳地连接到$ ads_3 $。我们在NS-NS扇区中构建无质量的闭合字符串状态词直接算子，计算相应的两点相关函数，并从4+1个维边界场理论的观点中讨论我们结果的全息解释。压实$ \ mathbb {t}^4 $上的理论，我们表明单个长字符串的频谱与单位绕组的频谱与$ t \ bar {t} $变形的cft $ _2 $ spectrum一致。我们还使用世界表技术计算双1+1尺寸非符号边界场理论的操作员的相关函数。
We build a novel time-like coset sigma-model describing type-II superstring theory in a charged rotating black-brane background that interpolates between a locally $AdS_3$ in the IR and a linear-dilaton geometry in the UV. This allows one to perform a systematic study of holography in non-AdS backgrounds which are smoothly connected to $AdS_3$. We construct massless closed string states vertex operators in the NS-NS sector, calculate the corresponding two-point correlation functions, and discuss holographic interpretation of our results from 4+1 dimensional boundary field theory point of view. Compactifying the theory on $\mathbb{T}^4$, we show that the spectrum of a single long string with unit winding agrees with the spectrum of a CFT$_2$ deformed by $T\bar{T}$. We also calculate correlation functions of operators of the dual 1+1 dimensional non-conformal boundary field theory using world-sheet techniques.
