标题： Challenging event horizons with spin (3/2) fields

摘要： 我们尝试通过用无质量自旋(3/2)场扰动克尔黑洞来摧毁其事件视界。 我们通过结合吸收概率的显式形式以及由于测试场自能引起的回反作用效应，进行了详细的分析。 对于极端和接近极端的黑洞，大振幅的扰动中回反作用效应占主导地位。 然而，小扰动可以摧毁极端黑洞的事件视界，并使接近极端的黑洞更接近极端状态。 最终，接近极端的黑洞会达到某个阶段，使其可以被连续驱动至极端状态甚至超越。 自旋(3/2)场可以直接破坏宇宙审查猜想和黑洞动力学的第三定律。 这是由于费米子场不满足零能量条件。 因此，这一结果并不与宇宙审查猜想和黑洞力学定律对于满足零能量条件的扰动仍然有效这一事实相矛盾。 显示英文摘要

摘要： We attempt to destroy the event horizons of Kerr black holes by perturbing them with massless spin (3/2) fields. We carry out a detailed analysis by incorporating the explicit form of the absorption probabilities and backreaction effects due to the self energy of the test fields. For extremal and nearly extremal black holes, backreaction effects dominate for perturbations with large magnitudes. However, small perturbations can destroy the event horizons of extremal black holes and drive nearly extremal black holes closer to extremality. Eventually, nearly extremal black holes reach a certain stage where they can be continuously driven to extremality and beyond. Both the cosmic censorship conjecture and the third law of black hole dynamics can be violated by spin (3/2) fields. This directly follows from the fact that fermionic fields do not satisfy the null energy condition. Therefore this result does not contradict with the fact that cosmic censorship and the laws of black hole mechanics remain valid for perturbations satisfying the null energy condition.
