论文摘要
我们展示了如何从旋转的C-晶型时空中删除，该时期描述了加速的Kerr黑洞，这两个圆锥形奇异性。这可以通过将度量嵌入适当的Ehllers转换中来完成。外部旋转背景和黑洞之间的自旋旋转相互作用提供了加速度的来源，而无需杆或弦。使用Kerr/CFT对应关系的近地平线和双保形技术研究了新溶液的物理特性和熵。还分析了带电的案例：还会生成嵌入在漩涡宇宙中的reissner-nordstrom并加速嵌入在旋转宇宙中的Kerr-Newman太空时间。
We show how to remove from the rotating C-metric spacetime, which describes accelerating Kerr black holes, both conical singularities. This can be done by embedding the metric into a swirling gravitational universe, through a proper Ehlers transformation. The spin-spin interaction between the external rotational background and the black hole provides the source of the acceleration without the need of rods or strings. The physical properties and entropy of the new solution are studied using near horizon and dual conformal techniques of the Kerr/CFT correspondence. The charged case is also analysed: Accelerating Reissner-Nordstrom and Accelerating Kerr-Newman space-times embedded in a swirling universe are also generated.
