RSII模型中静态黑洞的解析解

Analytic solution for a static black hole in RSII model

De-Chang Dai, Dejan Stojkovic

摘要:

本文给出了在RSII模型中位于膜上的大黑洞(其视界半径大于AdS半径)的静态解。基于AdS/CFT猜想的一些论点认为,RSII模型中位于膜上的黑洞的解必须编码量子引力效应,因而不可能是静态的。我们证明了,静态的解决方案,可以找到,如果散装不是空的。对于我们发现的解,物质在体中分布的应力能量张量是物理的(即,它是非奇异的,能量密度和压力不违反任何能量条件)。然而,该解不能转化为类史瓦西形式,也不能还原为膜上的史瓦西解。我们还提出了其他两个相关的静态解决方案。最后,我们讨论了为什么到目前为止,在这种情况下,找到静态解决方案的数值方法失败,包括我们在这里找到的解决方案解析。

英文摘要:

We present here a static solution for a large black hole (whose horizon radius is larger than the AdS radius) located on the brane in RSII model. According to some arguments based on the AdS/CFT conjecture, a solution for the black hole located on the brane in RSII model must encode quantum gravitational effects and therefore can not be static. We demonstrated that a static solution can be found if the bulk is not empty. The stress energy tensor of the matter distribution in the bulk for the solution we found is physical (i.e. it is non-singular with the energy density and pressure not violating any energy conditions). However, the solution can not be transformed into the Schwarzschild-like form and does not reduce to the Schwarzschild solution on the brane. We also present two other related static solutions. At the end, we discuss why the numerical methods failed so far in finding static solutions in this context, including the solutions we found analytically here.
