块状IIA的6维表面缺陷

6d surface defects from massive type IIA

Giuseppe Dibitetto, Nicolò Petri

摘要:

我们提出了一个新的BPS流在最小的$\mathcal{N}=1$超重力在七个维度描述一个扭曲的$\textrm{AdS}_{3}$背景支持的“双音”配置文件的三种形式。此外,我们讨论了全息解释的上述解决方案中的缺陷$\textrm{SCFT}_{2}$内的6d $(1,0)$理论对偶的AdS在渐近区域。最后,我们提供了在有质量IIA型弦论中,上述缺陷CFT作为D2-和缠绕D4-膜终止于D 6-NS 5- D8漏斗的膜图像。

英文摘要:

We present a new BPS flow within minimal $\mathcal{N}=1$ supergravity in seven dimensions describing a warped $\textrm{AdS}_{3}$ background supported by a "dyonic" profile of the three-form. Furthermore, we discuss the holographic interpretation of the above solution in terms of a defect $\textrm{SCFT}_{2}$ inside the 6d $(1,0)$ theory dual to the AdS in the asymptotic region. Finally we provide the brane picture of the aforementioned defect CFT as D2- and wrapped D4-branes ending on a D6 - NS5 - D8 funnel in massive type IIA string theory.
