We construct a supersymmetric NS5-brane wrapped on a twisted 5-sphere expanding in the $CP^3$ in $AdS_4\times CP^3$, with D0-brane charge. This configuration provides a realization of the stringy exclusion principle in terms of giant D0-branes. In the maximal case the twisted 5-sphere reduces to a $CP^2$ and its energy can be accounted for both by a bound state of $k$ D4-branes wrapping the $CP^2$ and a bound state of $N$ D0-branes, a realization on the gravity side of the symmetry of Young diagrams with $N$ rows and $k$ columns. We discuss some generalizations of this configuration in M-theory carrying angular momentum, some of them with an interpretation as giant gravitons. We provide the microscopical description that allows to explore the region of finite 't Hooft coupling.
Giant Gravitons on AdS_4 x CP^3 and their Holographic Three-point Functions
我们发现了AdS_4 x CP ^3中反对称巨引力子的一个简单参数化,它首先在arXiv:1108.3084 [hep-th]中构造,与ABJM理论中涉及两个双基本复标量场的反对称舒尔多项式对偶。使用这种参数化,我们评估在一个半经典的方法的三点函数的两个这样的巨引力子和一个点状引力子考虑极值和非极值配置。我们同样讨论了AdS_4 x CP ^3中对称巨引力子的情况。最后,我们给出了强耦合下ABJM中手征准素算符的平面三点函数的表达式,并发现在类点极限下,巨引力子三点函数的结果约化为该表达式.

本文用介电引力波描述了AdS_m x S^n中包含5个球的巨引力子组态,即AdS_4 x S ^7中的巨引力子组态和AdS_7 x S ^4中的对偶巨引力子组态.因此,我们总结了在hep-th/0207199中开始并在hep-th/0303183和hep-th/0406148中进行的计划,该计划旨在对AdS_m x S^n时空中的巨引力子进行微观描述。在我们的构造中,由于Myers介电效应,引力波扩展到模糊5-球上,这些模糊5-球被描述为模糊CP ^2上的S^1丛。这些模糊球表现为矩阵模型的解,而矩阵模型又表现为M理论引力波的作用量。我们的描述的有效性检查确认协议与阿贝尔描述的球面M5膜时,波的数量趋于无穷大。
