论文摘要
量子校正重力的有效作用包含巨大的自旋-2幽灵自由度,并接受了拓扑术语,该术语将纵向矢量的自由度伴随着巨大的自旋2的自由度,以与麦克斯韦的电磁作用。我们认为,在有其他不可观察的重量磁极的存在下,此拓扑术语会在黑洞上引起电荷,该电荷可以通过相关的电场和磁场进行探测。特别是,我们讨论了由于周围等离子体的同步辐射和超质量带电的黑洞的阴影而导致的带有Ligo带电的黑洞二元合并的电磁后续。
Quantum corrected effective action for gravity contains massive spin-2 ghost degrees of freedom and admits a topological term which couples longitudinal vector degrees of freedom of the massive spin-2 to Maxwell's electromagnetism. We argue that in the presence of otherwise unobservable gravimagnetic poles this topological term induces an electric charge on a black hole which can be probed through the associated electric and magnetic fields. In particular, we discuss the electromagnetic follow up from the LIGO-sensitive charged black hole binary coalescence due to the synchrotron radiation from the surrounding plasma and the shadow of super-massive charged black holes.
