Kerr-de Sitter黑洞的守恒电荷和热力学第一定律

Conserved Charges and First Law of Thermodynamics for Kerr-de Sitter Black Holes

Kamal Hajian

摘要:

最近,一个计算一般协变引力理论(黑洞)解的守恒荷的一般方法,在任意维和任意渐近行为已经被引入。利用这一方法,我们计算了Kerr-dS黑洞的质量和角动量。此外,对于任意视界的选择,导出了关联熵和热力学热力学第一定律。有趣的是,根据分析对所选宇宙学常数的不敏感性,该分析将四维(和其他)中旋转静止黑洞的热力学与AdS、平坦或dS渐近性统一起来。我们将分析扩展到包括电荷,即扩展到Kerr-Newman-dS黑洞。

英文摘要:

Recently, a general method for calculating conserved charges for (black hole) solutions to generally covariant gravitational theories, in any dimensions and with arbitrary asymptotic behaviors has been introduced. Equipped with this method, which can be dubbed as "solution phase space method," we calculate mass and angular momentum for the Kerr-dS black holes. Furthermore, for any choice of horizons, associated entropy and the first law of thermodynamics are derived. Interestingly, according to insensitivity of the analysis to the chosen cosmological constant, the analysis unifies the thermodynamics of rotating stationary black holes in 4 (and other) dimensions with either AdS, flat or dS asymptotics. We extend the analysis to include electric charge, i.e. to the Kerr-Newman-dS black holes.
