新质量引力中的全息重整化和应力张量

Holographic Renormalization and Stress Tensors in New Massive Gravity

Yongjoon Kwon, Soonkeon Nam, Jong-Dae Park, Sang-Heon Yi

摘要:

我们得到全息重整化的边界应力张量的三维新的大质量引力的参数空间中的一个特殊的点,使用所谓的Festhiman-Graham坐标与相关的计数器条款。通过对运动方程的线性化,得到了这些应力张量之间的相互作用。我们认为,全息重整化的自洽性决定了反条款的非物理的歧义。利用这些重整化的应力张量在Februaryman-Graham坐标下得到了对偶CFT的中心荷,以及某些$AdS$黑洞解的质量和角动量.这些结果与以前用其他方法得到的结果一致。通过对新质量引力的February man-Graham展开式的研究,揭示了高曲率引力的某些方面。

英文摘要:

We obtain holographically renormalized boundary stress tensors with the emphasis on a special point in the parameter space of three dimensional new massive gravity, using the so-called Fefferman-Graham coordinates with relevant counter terms. Through the linearized equations of motion with a standard prescription, we also obtain correlators among these stress tensors. We argue that the self-consistency of holographic renormalization determines counter terms up to unphysical ambiguities. Using these renormalized stress tensors in Fefferman-Graham coordinates, we obtain the central charges of dual CFT, and mass and angular momentum of some $AdS$ black hole solutions. These results are consistent with the previous ones obtained by other methods. In this study on the Fefferman-Graham expansion of new massive gravity, some aspects of higher curvature gravity are revealed.
