论文摘要
我们通过从Infinity中发送测试粒子来测试2+1个维度中的静态带电的Dilaton黑洞。我们得出了极端和几乎极端黑洞的可能性和通用性。我们的分析还表明，与几乎极端的Baunados-Teitelboim-Zanelli，Kerr和Reissner-Nordström黑洞相比，几乎可以将几乎极值的Dilaton黑洞连续驱动到极端性及以后，这些黑洞被离散的跳跃过度繁殖或过度充电。因此，宇宙审查制度的弱形式和黑洞热力学的第三定律在2+1维的带电dilaton黑洞与测试粒子的相互作用中都违反了。我们还推出了从黑洞到裸露的奇异性的过渡中，热容量消失或分歧没有任何点。可能不会发生可能阻止裸奇异物形成的相变。
We test whether static charged dilaton black holes in 2+1 dimensions can be turned into naked singularities, by sending in test particles from infinity. We derive that overcharging is possible and generic for both extremal and nearly extremal black holes. Our analysis also imply that nearly extremal charged dilaton black holes can be continuously driven to extremality and beyond, unlike nearly extremal Baunados-Teitelboim-Zanelli, Kerr and Reissner-Nordström black holes which are overspun or overcharged by a discrete jump. Thus the weak form of the cosmic censorship conjecture and the third law of black hole thermodynamics are both violated in the interaction of charged dilaton black holes in 2+1 dimensions, with test particles. We also derive that there exists no points where the heat capacity vanishes or diverges in the transition from black holes to naked singularities. The phase transitions that could potentially prevent the formation of naked singularities do not occur.
