论文摘要

我们在超级构建IIA字符串理论(大容量,小$ G_S $)制度中构建AD $ _4 $通量真空,包括O6平面的反射。我们的解决方案是DeWolfe,Giryavets,Kachru和Taylor在Calabi-Yau Erientifolds上的涂片解决方案的局部版本,以及其他作品。我们发现这些溶液中的O平面反应会产生翘曲,这是变化的DILATON,非关闭的RR场强度和内部曲率。就像他们的涂片对应物一样,局部解决方案允许稳定的模量,对字符串校正的参数控制以及ADS和KK量表之间的参数分离。此外,我们的明确表达式使涂抹的解决方案应近似于大批量,小$ g_s $限制的普遍传说。最后,我们的解决方案似乎违反了最近关于超对称ADS真空的尺度分离的宣传猜想。我们做出了一个简单的观察,解释了为什么这些解决方案与弦理论中的大多数其他ADS解决方案相反。

We construct AdS$_4$ flux vacua of type IIA string theory in the supergravity (large volume, small $g_s$) regime, including the backreaction of O6-planes. Our solutions are the localized versions of the smeared solutions on Calabi-Yau orientifolds studied by DeWolfe, Giryavets, Kachru and Taylor and in other works. We find that the O-plane backreaction in these solutions generates warping, a varying dilaton, non-closed RR field strengths and internal curvature. Just like their smeared counterparts, the localized solutions admit stabilized moduli, a parametric control over string corrections and a parametric separation between the AdS and KK scales. Our explicit expressions furthermore make precise the common lore that smeared solutions should approximate the exact ones in the large-volume, small-$g_s$ limit. Finally, our solutions appear to violate a recent swampland conjecture about an absence of scale separation in supersymmetric AdS vacua. We make a simple observation explaining why this happens in these solutions in contrast to most other AdS solutions in string theory.
