论文摘要
我们发现Abelian仪表域将其双重复制到一大类的黑洞间距，并带有球形拓扑，称为Kerr-nut-（a）DS家族。使用多币芯处方，我们扩展了以前的双复制结构，用于任意旋转一般尺寸黑洞，以包括螺母电荷和任意的宇宙常数。在所有情况下，这些单复制量规字段都是“对齐的字段”，因为它们的非零组件与生成时空杀伤结构的主要张量对齐。在五个维度中，我们还通过Weyl Double Coppy程序得出相同的单拷贝场强度。
We find Abelian gauge fields that double copy to a large class of black hole spacetimes with spherical horizon topology known as the Kerr-NUT-(A)dS family. Using a multi-Kerr-Schild prescription, we extend the previously-known double copy structure for arbitrarily rotating general dimension black holes, to include NUT charges and an arbitrary cosmological constant. In all cases, these single copy gauge fields are 'aligned fields', because their nonzero components align with the principal tensor which generates the Killing structure of the spacetime. In five dimensions, we additionally derive the same single-copy field strengths via the Weyl double copy procedure.
