论文摘要
在本文中，我们研究了一个被完美的液体暗物质包围的旋转黑洞的热力学特征。我们通过考虑压力与宇宙常数之间的已知关系来分析黑洞的临界行为。我们表明，黑洞承认一阶相变，旋转和完美的流体暗物质参数都对临界数量产生了重大影响。我们还引入了与完美流体暗物质有关的新的临时压力，并找到了一阶范德华（例如相变）。此外，使用第六阶WKB方法，我们研究了静态球形对称黑洞的无质量标量准模式（QNM）。使用有限差方案，还讨论了QNM的动力学演化，以了解角动量和泛音参数的不同值。
In this paper, we study the thermodynamic features of a rotating black hole surrounded by perfect fluid dark matter. We analyze the critical behavior of the black hole by considering the known relationship between pressure and cosmological constant. We show that the black hole admits a first order phase transition and, both rotation and perfect fluid dark matter parameters have a significant impact on the critical quantities. We also introduce a new ad hoc pressure related to the perfect fluid dark matter and find a first order van der Waals like phase transition. In addition, using the sixth order WKB method, we investigate the massless scalar quasinormal modes (QNMs) for the static spherically symmetric black hole surrounded by dark matter. Using the finite difference scheme, the dynamical evolution of the QNMs is also discussed for different values of angular momentum and overtone parameters.
