论文摘要
在本文中,我们研究了连形的Weyl重力范式中的黑洞熵普遍性。我们首先要通过计算特定真空和非效率溶液的熵来做到这一点,该溶液以前尚未通过Nöther电流方法和Wald的熵公式在共形的Weyl重力中探索。对于真空案例,我们探索了极端KERR公制附近的近乎地平线,这也是一种真空解决方案,用于共形韦尔重力,以前在这种情况下未研究。对于非vacuum情况,我们将共形的Weyl重力场方程与接近地平线(线性)$ u(1)$计势并分析相应的解决方案。我们强调了我们所研究的不同对称性的黑洞解决方案之间的黑洞熵的非宇宙性。然而,尽管非宇宙性,但各自的黑洞熵与瓦尔德(Wald)的熵公式一致。最后,尽管非通行性,我们还是对我们独特的非vacuum解决方案之一的近地平线CFT进行了评论。由于非大学性,我们必须引入一个参数(类似于LQG中的熵计算),我们也称之为$γ$并与Weyl异常系数有关。该结构遵循近地平线的$ ads_2/cft_1 $对应关系,可以计算所选的非Vacuum保形的Weyl黑洞的完整渐近对称组及其近地平线量子CFT二元。我们以讨论和未来工作的前景为首。
In this paper we study black hole entropy universality within the Conformal Weyl gravity paradigm. We do this by first computing the entropy of specific vacuum and non-vacuum solutions, previously unexplored in Conformal Weyl gravity via both the Nöther current method and Wald's entropy formula. For the vacuum case, we explore the near horizon near extremal Kerr metric, which is also a vacuum solution to Conformal Weyl gravity and not previously studied in this setting. For the non-vacuum case we couple the conformal Weyl gravity field equations to a near horizon (linear) $U(1)$ gauge potential and analyze the respective found solutions. We highlight the non-universality of black hole entropy between our studied black hole solutions of varying symmetries. However despite non-universality, the respective black hole entropies are in congruence with Wald's entropy formula for the specific gravity theory. Finally and despite non-universality, we comment on the construction of a near horizon CFT dual to one of our unique non-vacuum solutions. Due to the non-universality, we must introduce a parameter (similarly to entropy calculations in LQG) which we also call $γ$ and relating to the Weyl anomaly coefficient. The construction follows an $AdS_2/CFT_1$ correspondence in the near horizon, which enables the computation of the full asymptotic symmetry group of the chosen non-vacuum conformal Weyl black hole and its near horizon quantum CFT dual. We conclude with a discussion and outlook for future work.
