高维带电旋转膨胀黑洞

Higher Dimensional Charged Rotating Dilaton Black Holes

A. Sheykhi, M. Allahverdizadeh

摘要:

本文给出了在渐近平坦和渐近(反)-de Sitter时空背景下,具有$N = [(n -1)/2]$独立旋转参数的黑洞上$n$ -维带电慢旋转粒子的度规,它与$N$正交旋转平面有关.对于任意的强子耦合常数,我们确定了这样一个黑洞的质量、角动量和旋磁比。我们发现旋磁比的大小主要取决于声子耦合常数$α$,并且在任意维度上随$α$的增大而减小.

英文摘要:

In this paper, we present the metric for the $n$-dimensional charged slowly rotating dilaton black hole with $N = [(n -1)/2]$ independent rotation parameters, associated with $N$ orthogonal planes of rotation in the background of asymptotically flat and asymptotically (anti)-de Sitter spacetime. The mass, angular momentum and the gyromagnetic ratio of such a black hole are determined for the arbitrary values of the dilaton coupling constant. We find that the gyromagnetic ratio crucially depends on the dilaton coupling constant, $α$, and decreases with increasing $α$ in any dimension.
