对准场对Kerr-NUT-(A)dS的双重复制

Aligned Fields Double Copy to Kerr-NUT-(A)dS

Samarth Chawla, Cynthia Keeler

AI总结:

本文利用多重Kerr-Schild方案将对准阿贝尔规范场的双重复制结构推广到含NUT荷和任意宇宙学常数的Kerr-NUT-(A)dS黑洞族,并在五维中用Weyl双重复制验证了单复制场强。

摘要:

我们找到了阿贝尔规范场,它们可双重复制到一大类具有球面视界拓扑的黑洞时空,即Kerr-NUT-(A)dS族。利用多重Kerr-Schild方案,我们将先前已知的任意旋转一般维度黑洞的双重复制结构推广到包含NUT荷和任意宇宙学常数的情况。在所有情形中,这些单复制规范场都是“对准场”,因为它们的非零分量与生成时空Killing结构的主张量对准。在五维中,我们还通过Weyl双重复制程序导出了相同的单复制场强。

英文摘要:

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.
