一个(运行)螺栓的新原因
A (Running) Bolt for New Reasons
摘要:
以四维欧氏史瓦西度规为基空间,对其进行“磁化”,构造了一个无规范五维超引力的四参数光滑、无水平、定常解族.然后,我们推广到一个五参数的家庭的基础上欧几里德克尔-陶布-博尔特。这些“运行螺栓”解决方案必须是非静态的。它们的电荷和质量与具有经典大视界面积的非极值黑洞相同。此外,在一定范围内,它们的质量会随着电荷的增加而减少。这些解决方案的存在支持的想法,解决了非极端黑洞的奇异性的低质量模式,纠正大尺度(视界大小)的经典黑洞解的奇异性。
英文摘要:
We construct a four-parameter family of smooth, horizonless, stationary solutions of ungauged five-dimensional supergravity by using the four-dimensional Euclidean Schwarzschild metric as a base space and "magnetizing" its bolt. We then generalize this to a five-parameter family based upon the Euclidean Kerr-Taub-Bolt. These "running Bolt" solutions are necessarily non-static. They also have the same charges and mass as a non-extremal black hole with a classically-large horizon area. Moreover, in a certain regime their mass can decrease as their charges increase. The existence of these solutions supports the idea that the singularities of non-extremal black holes are resolved by low-mass modes that correct the singularity of the classical black hole solution on large (horizon-sized) scales.
