微扰带电旋转的5D Einstein-Maxwell黑洞

Perturbative Charged Rotating 5D Einstein-Maxwell Black Holes

Francisco Navarro-Lerida

摘要:

我们提出了具有球视界拓扑的微扰带电旋转5维Einstein-Maxwell黑洞。电荷Q是微扰参数,微扰进行到第四阶。给出了这些黑洞的有关物理性质的表达式。旋磁比g,特别是,明确示出为在高阶中是非恒定的,并且因此偏离其最低阶值g=3。微扰解析解与非微扰数值解的比较显示出显著的一致性。

英文摘要:

We present perturbative charged rotating 5D Einstein-Maxwell black holes with spherical horizon topology. The electric charge Q is the perturbative parameter, the perturbations being performed up to 4th order. The expressions for the relevant physical properties of these black holes are given. The gyromagnetic ratio g, in particular, is explicitly shown to be non-constant in higher order, and thus to deviate from its lowest order value, g=3. Comparison of the perturbative analytical solutions with their non-perturbative numerical counterparts shows remarkable agreement.
