Brans-Dicke-Maxwell理论中的慢转黑洞

Slowly Rotating Black Holes in Brans-Dicke-Maxwell Theory

H. Alavirad

摘要:

本文在具有二次势的Brans-Dicke-Maxwell理论中构造了一类(n+1)维慢转黑洞解的$(n\geq4)$.这些解可以表示具有内、外事件视界的黑洞、极端黑洞和裸奇点,它们既不是渐近平坦的,也不是(反)de Sitter的.我们计算欧几里德作用量,并利用它来获得守恒量和热力学量,如熵,它不遵守面积定律。我们还计算了这类黑洞的角动量和旋磁比,其中旋磁比在Brans-Dicke理论中与爱因斯坦理论相比有所修改。

英文摘要:

In this paper, we construct a class of (n+1)-dimensional $(n\geq4)$ slowly rotating black hole solutions in Brans-Dicke-Maxwell theory with a quadratic potential. These solutions can represent black holes with inner and outer event horizons, an extreme black hole and a naked singularity and they are neither asymptotically flat nor (anti)-de Sitter. We compute the Euclidean action and use it to obtain the conserved and thermodynamics quantities such as entropy, which does not obey the area law. We also compute the angular momentum and the gyromagnetic ratio for these type of black holes where the gyromagnetic ratio is modified in Brans-Dicke theory compared to the Einstein theory.
