论文摘要
在这项工作中，我们认为在四个维度上被各向异性流体包围的黑洞。我们首先研究了这些解决方案的因果结构，显示了与Reissner-Nordström-De保姆黑洞的某些相似性和差异。另外，我们考虑在此背景几何形状上标量扰动并计算相应的准模式。此外，我们讨论了扰动的后期行为，发现了一个有趣的新功能，即存在亚域的幂律尾术语。同样，我们使用砖墙方法来计算Bekenstein熵结合，并将第一个半经典校正与黑洞熵进行，显示它们的普遍性。最后，我们还讨论了模型的热力学稳定性。
In this work we consider black holes surrounded by anisotropic fluids in four dimensions. We first study the causal structure of these solutions showing some similarities and differences with Reissner-Nordström-de Sitter black holes. In addition, we consider scalar perturbations on this background geometry and compute the corresponding quasinormal modes. Moreover, we discuss the late-time behavior of the perturbations finding an interesting new feature, i.e., the presence of a subdominant power-law tail term. Likewise, we compute the Bekenstein entropy bound and the first semiclassical correction to the black hole entropy using the brick wall method, showing their universality. Finally, we also discuss the thermodynamical stability of the model.
