Michael Butler, Masoud Ghezelbash

AI总结:

该研究针对带标量场与高斯-博内不变量非最小耦合的四维爱因斯坦-麦克斯韦理论,结合渐近与视界附近微扰展开,用数值方法求得带NUT扭的带标量荷黑洞解,并分析了参数对解的影响。

摘要:

本文研究了一类四维爱因斯坦-麦克斯韦理论,该理论与标量场及高斯-博内不变量存在非最小耦合。我们主要采用数值方法寻找带NUT扭的理论解,明确求出了所有场方程的数值解。为得到恰当自洽的数值解,我们使用了场在渐近区域以及视界附近的微扰展开。这些解描述了带标量荷的NUT型黑洞,其性质也显式依赖于非最小耦合常数的取值。我们针对理论中所有现存参数,对解进行了详细的数值分析。

英文摘要:

In this article, we consider a class of four-dimensional Einstein-Maxwell theory which is coupled non-minimally to a scalar field and the Gauss-Bonnet invariant. We mainly use the numerical methods to find the solutions to the theory, with the NUT twist. We find explicitly the numerical solutions to all of the field equations. To find the appropriate consistent numerical solutions, we use the the perturbative expansion of the fields asymptotically, as well as near horizon. The solutions describe the NUTty black holes with the scalar charge which also depend explicitly on the values of the non-minimal coupling constants. We provide a detailed numerical analysis of the solutions in terms of all existing parameters of the theory.
