论文摘要
我们表明，可以根据世界表的有效行动来解释确切的Kerr解决方案的Newman-Janis Shift属性。这既有重力，又适用于单拷贝$ \ sqrt {\ text {kerr}} $电型动力学中的解决方案。在运动方程级别上，我们表明纽曼 - 贾尼斯（Newman-Janis）的转移也适用于克尔黑洞（Kerr Black Hole）的主要相互作用。这些领先的相互作用使用手性经典运动方程式在散射振幅中熟悉的旋转器方法的帮助下方便地描述。
We show that the Newman-Janis shift property of the exact Kerr solution can be interpreted in terms of a worldsheet effective action. This holds both in gravity, and for the single-copy $\sqrt{\text{Kerr}}$ solution in electrodynamics. At the level of equations of motion, we show that the Newman-Janis shift holds also for the leading interactions of the Kerr black hole. These leading interactions are conveniently described using chiral classical equations of motion with the help of the spinor-helicity method familiar from scattering amplitudes.
