In the framework of the new version of the gedanken experiments proposed by Sorce and Wald, we investigate the weak cosmic censorship conjecture (WCCC) for an Einstein–Maxwell–Dilaton–Axion (EMDA) black hole. Our result shows that no violations of WCCC can occur with the increase of the background solution parameters for this near-extremal EMDA black hole when the second-order correction of the perturbations is taken into account. Namely, the near-extremal EMDA black hole cannot be over-charged or over-spun.

通过爱因斯坦-麦克斯韦-狄拉顿-轴子黑洞的 gedanken 实验检验弱宇宙审查猜想

在 Sorce 和 Wald 提出的新版 gedanken 实验的框架下,我们研究了爱因斯坦-麦克斯韦-膨胀轴子 (EMDA) 黑洞的弱宇宙审查猜想 (WCCC)。我们的结果表明,当考虑到扰动的二阶校正时,随着这个近极值 EMDA 黑洞背景解参数的增加,不会发生 WCCC 违规。也就是说,近极值 EMDA 黑洞不能被过度充电或过度旋转。
