论文摘要
由于与Reissner-Nordstrom（RN）黑洞的DE Sitter（DS）时空的黑洞和宇宙学范围并非彼此独立，这是由重力效应引起的，因此应考虑两个范围之间的相互作用。基于此，通过引入交互式熵，RN-DS时空类似于具有各种热力学量的热力学系统，其中热力学定律仍然存在。在我们的工作中，RN-DS时空的热力学特性在诱导的相空间中被映射到类似于ADS黑洞中的相位空间。观察到高电位和低电势黑洞相之间的RN-DS时空的相变。与普通的热力学系统相比，还检查了有关Joule-Thomson扩展和关键指数的相似行为。最后，提出了两个存在阶段的标态曲率，以揭示RN-DS时空中的基本微观结构和相变的性质，该曲线从观察性的角度开设了一个新窗口，以研究DS时空，从观察性的角度来看。
Since the black hole and cosmological horizons in the de Sitter (dS) spacetime with the Reissner-Nordstrom (RN) black hole are not independent to each other, which is caused by the gravitational effect, the interplay between two horizons should be considered. Based on this, by introducing the interactive entropy the RN-dS spacetime is analogous to a thermodynamic system with various thermodynamic quantities, in which the thermodynamic laws still hold on. In our work, the thermodynamic properties of the RN-dS spacetime are mapped out in the induced phase space, which are similar to that in AdS black holes. The phase transition of the RN-dS spacetime between the high-potential and the low-potential black hole phases is observed. Compared with an ordinary thermodynamic system, the similar behaviors about the Joule-Thomson expansion and the critical exponents are also checked out. Finally, the scalar curvature of two existent phases are presented to reveal the underlying microstructure and nature of phase transition in the RN-dS spacetime, which opens a new window to investigate the dS spacetime with black holes from a observational perspective.
