The new version of the gedanken experiments proposed by Sorce and Wald are designed to test the validity of the weak cosmic censorship conjecture (WCCC) by overspinning or overcharging the Kerr-Newman black hole in Einstein-Maxwell gravity. Following their setup, in this paper, we investigate the WCCC in the higher-dimensional charged black hole with a nonlinear electrodynamics source. We derive the first and seconder order perturbation inequalities of the charged collision matter based on the Iyer-Wald formalism as well as the null energy conditions, and show that they share the similar form as that in Einstein-Maxwell gravity. As a result, we find that the static higher-dimensional nonlinear electrodynamics (HDNL) black holes cannot be overcharged after considering these two inequalities. Our result might indicate the validity of WCCC for more general HNDL and related systems.

具有非线性电动力源的高维黑洞中的弱宇宙检查猜想

Sorce和Wald提出的新版gedanken实验旨在通过对爱因斯坦-麦克斯韦引力的Kerr-Newman黑洞过度旋转或过度充电来测试弱宇宙审查猜想(WCCC)的有效性。按照它们的设置,在本文中,我们将使用非线性电动力源研究高维带电黑洞中的WCCC。我们基于艾耶-瓦尔德形式主义和零能条件,推导了带电碰撞物质的一阶和二阶摄动不等式,并证明它们具有与爱因斯坦-麦克斯韦引力相似的形式。结果,我们发现静态高维非线性电动力学(HDNL)黑洞在考虑了这两个不等式后不会过度充电。
