Abstract

This paper is about the extended thermodynamics of AdS black holes and its relation to CFT thermodynamics. The logarithmic term of the central charge is interpreted as black hole entropy. We have to obtain a modified Friedmann equation from the Smarr formula. We find that the AdS radius is the critical shadow radius. We obtain the Hawking-Bekenstein formula with logarithmic corrections, which depends on the central charge. The real gas in AdS is a dual of an ideal gas in CFT. This work can be extended to the AdS-Kerr black holes.

熵作为中心电荷的对数项和AdS/CFT对应中的修正Friedmann方程

本文讨论了AdS黑洞的扩展热力学及其与CFT热力学的关系。中心电荷的对数项被解释为黑洞熵。我们必须从斯马尔公式中得到一个修正的弗里德曼方程。我们发现AdS半径是临界阴影半径。我们得到了具有对数校正的Hawking Bekenstein公式，该公式取决于中心电荷。AdS中的真实气体是CFT中理想气体的对偶。这项工作可以推广到AdS-Kerr黑洞。

期刊介绍： ACS Central Science publishes significant primary reports on research in chemistry and allied fields where chemical approaches are pivotal. As the first fully open-access journal by the American Chemical Society, it covers compelling and important contributions to the broad chemistry and scientific community. "Central science," a term popularized nearly 40 years ago, emphasizes chemistry's central role in connecting physical and life sciences, and fundamental sciences with applied disciplines like medicine and engineering. The journal focuses on exceptional quality articles, addressing advances in fundamental chemistry and interdisciplinary research.
