大质量重力场的流体/重力对应

Fluid/gravity correspondence for massive gravity

Wen-Jian Pan, Yong-Chang Huang

摘要:

在本文中,我们研究了流体/重力对应的框架下,大量的爱因斯坦引力。将引力质量项视为有效的能量动量张量,利用类时超曲面上的类Petrov-like边界条件,我们发现在近视界和非相对论极限下,大质量引力的扰动效应可以完全由截断面上的不可压纳维-斯托克斯方程控制.此外,我们还简明地计算了两个大质量爱因斯坦引力理论的动力学粘度与熵密度之比,发现它们仍然饱和Kovtun-Son-Starbow(KSS)束缚。

英文摘要:

In this paper, we investigate the fluid/gravity correspondence in the framework of massive Einstein gravity. Treating the gravitational mass terms as an effective energy-momentum tensor and utilizing the Petrov-like boundary condition on a timelike hypersurface, we find that the perturbation effects of massive gravity in bulk can be completely governed by the incompressible Navier-Stokes equation living on the cutoff surface under the near horizon and nonrelativistic limits. Furthermore, we have concisely computed the ratio of dynamical viscosity to entropy density for two massive Einstein gravity theories, and found that they still saturate the Kovtun-Son-Starinets (KSS) bound.
