BPS表面算符的全息照相

Holography of BPS surface operators

Eunkyung Koh, Satoshi Yamaguchi

摘要:

本文研究了四维N=4超杨-米尔斯理论中的一类伸缩不变BPS曲面算子及其在AdS_5 × S^5上的IIB型弦论中的全息展开.首先,我们以1/4 BPS曲面算符为例,从全息的观点对其进行了详细的研究。这个曲面算子的引力对偶是一个由全纯子流形刻画的D3-膜。从规范理论和引力两个方面检验了超对称性和真空期望值。我们还计算了两侧的手征原算符的关联函数,发现很好的一致性。接下来,我们考虑更一般的伸缩不变BPS曲面算子。提出了这些算子的引力估计。

英文摘要:

We study a class of dilatation invariant BPS surface operators in 4-dimensional N=4 Super Yang-Mills theory and their holographic duals in type IIB string theory in AdS_5 x S^5. First we take an example of 1/4 BPS surface operator and study it in detail from the holographic point of view. The gravity dual of this surface operator is a D3-brane characterized by a holomorphic submanifold. The supersymmetry and vacuum expectation value are checked in both the gauge theory side and the gravity side. We also calculate the correlation functions with the chiral primary operators in both sides and find good agreement. Next we consider more general dilatation invariant BPS surface operators. The gravity duals of those operators are proposed.
