高阶近似下的Gedanken实验:几乎极端的Reissner-Nordstrom黑洞不会被过度充电

Gedanken experiments at high-order approximation: nearly extremal Reissner-Nordstrom black holes cannot be overcharged

Xin-Yang Wang, Jie Jiang

摘要:

利用Sorce和Wald提出的新版本的gedanken实验,在物质场微扰的二级近似下研究了黑洞的弱宇宙监督猜想(WCCC).然而,只考虑扰动直到二阶近似是不完整的,因为存在一个最优选项,使得事件视界的存在条件在二阶处消失。对于这种情况,我们无法判断WCCC是否满足此订单。在我们的研究中,一般地导出了$k$阶扰动不等式。利用这些不等式,我们在高阶近似下研究了近似极值Reissner-Nordstöm黑洞的WCCC.结果表明,WCCC不能违反后,扰动。从这个结果可以看出,对于近极值RN黑洞,WCCC在微扰水平上是严格满足的。

英文摘要:

The new version of the gedanken experiment proposed by Sorce and Wald has been used to examine the weak cosmic censorship conjecture (WCCC) for black holes at the second-order approximation of the matter fields perturbation. However, only considering the perturbation until the second-order approximation is incomplete because there is an optimal option such that the existing condition of the event horizon vanishes at second-order. For this circumstance, we cannot judge whether the WCCC is satisfied at this order. In our investigation, the $k$th-order perturbation inequality is generally derived. Using the inequalities, we examine the WCCC for nearly extremal Reissner-Nordstöm black holes at higher-order approximation. It is shown that the WCCC cannot be violated yet after the perturbation. From this result, it can be indicated that the WCCC is strictly satisfied at the perturbation level for nearly extremal RN black holes.
