论文摘要
我们研究了二维(2D)重力模型中黑洞的线性标量扰动,并特别强调了Jackiw-Teitelboim(JT)重力。我们获得了JT重力中单层黑色孔的准模式频率的精确表达,然后使用Horowitz-Hubeny方法进行数值验证。对于2D Reissner-Nordström类似于解决方案,我们发现使用我们计算出鹰的光谱的无质量标量波方程将减小到汇合的heun方程。最后,我们考虑了尺寸降低的Bañados-teitelboim-Zanelli(BTZ)黑洞,并获得外部和内部准模式。 Cauchy Horizon附近的标量场的动力学模仿了通常的BTZ黑洞的行为,表明可能违反了在几乎极端极限中对强宇宙审查的猜想。但是,量子效应似乎可以挽救强大的宇宙审查制度。
We study linear scalar perturbations of black holes in two-dimensional (2D) gravity models with a particular emphasis on Jackiw-Teitelboim (JT) gravity. We obtain an exact expression of the quasinormal mode frequencies for single horizon black holes in JT gravity and then verify it numerically using the Horowitz-Hubeny method. For a 2D Reissner-Nordström like solution, we find that the massless scalar wave equation reduces to the confluent Heun equation using which we calculate the Hawking spectra. Finally, we consider the dimensionally reduced Bañados-Teitelboim-Zanelli (BTZ) black hole and obtain the exterior and interior quasinormal modes. The dynamics of a scalar field near the Cauchy horizon mimics the behavior of the same for the usual BTZ black hole, indicating a possible violation of the strong cosmic censorship conjecture in the near extreme limit. However, quantum effects seem to rescue strong cosmic censorship.
