Einstein-Gauss-Bonnet引力的大D膜范式

The large D Membrane Paradigm For Einstein-Gauss-Bonnet Gravity

Arunabha Saha

摘要:

我们发现在EGB引力中与黑洞对偶的膜的运动方程在大D区域达到1/D的领先阶。我们还找到了EGB方程的度量解的第一次领导阶在1/D的膜变量。我们提出了一个薄膜的世界体积应力张量,其守恒方程等价于首阶薄膜方程。我们还从静态圆膜的线性涨落计算出了EGB引力中静态黑洞的轻准简正模谱。利用EGB引力的膜方程,得到了稳态黑洞的有效方程和黑弦位形的线性化谱的谱,所有结果在Gauss-Bonnet参数下都是线性的。

英文摘要:

We find the equations of motion of membranes dual to the black holes in Einstein-Gauss-Bonnet (EGB) gravity to leading order in 1/D in the large D regime. We also find the metric solutions to the EGB equations to first subleading order in 1/D in terms of membrane variables. We propose a world volume stress tensor for the membrane whose conservation equations are equivalent to the leading order membrane equations. We also work out the light quasi-normal mode spectrum of static black holes in EGB gravity from the linearised fluctuations of static, round membranes. Also, the effective equations for stationary black holes and the spectrum of linearised spectrum about black string configurations has been obtained using the membrane equation for EGB gravity.All our results are worked out to linear order in the Gauss-Bonnet parameter.
