摘要

证明了复坐标变换将陶布-纽曼-非-坦布里诺瞬间度规映射为克尔-柴尔德度规。这个度规包含了半无限线缺陷作为狄拉克弦的引力类比，很像最初的度规。此外，它促进了电磁学中自对偶dyon的经典双复制对应的三种版本，其中一种涉及非局部算符。简要地指出了与纽曼-詹尼斯算法的相关性。2025年由美国物理学会出版

Single Kerr-Schild metric for Taub-NUT instanton

It is shown that a complex coordinate transformation maps the Taub-Newman-Unti-Tamburino instanton metric to a Kerr-Schild metric. This metric involves a semi-infinite line defect as the gravitational analog of the Dirac string, much like the original metric. Moreover, it facilitates three versions of classical double copy correspondence with the self-dual dyon in electromagnetism, one of which involves a nonlocal operator. The relevance to the Newman-Janis algorithm is briefly noted.
