突现Sasaki-Einstein几何与AdS/CFT

Emergent Sasaki-Einstein geometry and AdS/CFT

Robert J. Berman, Tristan C. Collins, Daniel Persson

摘要:

我们考虑具有最小超对称性的五维Anti-De Sitter空间$AdS_{5}$中的超引力,该空间由五维紧致流形$M$上的Sasaki-Einstein度量编码。我们的主要结果揭示了Sasaki-Einstein度规是如何从对偶CFT中的正则态中出现的,该对偶CFT由四维Minkowski空间$\mathbb{R}^{3,1}$中的超共形规范理论定义,在t 'Hooft极限中,秩$N$趋于无穷大。我们得到明确的有限$N-$近似的佐佐木-爱因斯坦度规,表示在一个典型的(即背景自由)的BPS状态的规范理论方面。我们还提供了一个弦论解释的BPS-状态的问题,这揭示了新的光以前注意到的有趣的巨引力子的对偶性。

英文摘要:

We consider supergravity in five-dimensional Anti-De Sitter space $AdS_{5}$ with minimal supersymmetry, encoded by a Sasaki-Einstein metric on a five-dimensional compact manifold $M$. Our main result reveals how the Sasaki-Einstein metric emerges from a canonical state in the dual CFT, defined by a superconformal gauge theory in four dimensional Minkowski space $\mathbb{R}^{3,1}$in the t'Hooft limit where the rank $N$ tends to infinity. We obtain explicit finite $N-$approximations to the Sasaki-Einstein metric, expressed in terms of a canonical (i.e. background free) BPS-state on the gauge theory side. We also provide a string theory interpretation of the BPS-state in question, which sheds new light on the previously noted intriguing duality of giant gravitons.
