自旋矩阵理论中的巨引力子相互作用

Interacting Giant Gravitons from Spin Matrix Theory

Troels Harmark

摘要:

利用非阿贝尔的DBI作用量,我们找到了一个有效的矩阵模型,它描述了在AdS_5 x S^5的AdS部分中,在高能时,S^5上有两个角动量,弱相互作用的巨引力子包裹在三个球上的动力学。同时我们考虑了\CN = 4的超杨-米尔斯理论在某一么正性界附近的极限,在那里它简化为称为SU(2)自旋矩阵理论的量子力学理论。我们发现,在弦论方面描述巨引力子的完全相同的矩阵模型也提供了自旋矩阵理论在强耦合和大能量极限下的有效描述。因此,我们能够将AdS_5 × S^5上D膜的非超对称动力学与\CN = 4的超杨-米尔斯理论中的有限N态在么正性界附近相匹配。

英文摘要:

Using the non-abelian DBI action we find an effective matrix model that describes the dynamics of weakly interacting giant gravitons wrapped on three-spheres in the AdS part of AdS_5 x S^5 at high energies with two angular momenta on the S^5. In parallel we consider the limit of \CN=4 super Yang-Mills theory near a certain unitarity bound where it reduces to the quantum mechanical theory called SU(2) Spin Matrix Theory. We show that the exact same matrix model that describes the giant gravitons on the string theory side also provides the effective description in the strong coupling and large energy limit of the Spin Matrix Theory. Thus, we are able to match non-supersymmetric dynamics of D-branes on AdS_5 x S^5 to a finite-N regime in \CN=4 super Yang-Mills theory near a unitarity bound.
