多极展开的双重复制

The double copy of the multipole expansion

Erick Chacón, Andres Luna, Chris D. White

摘要:

我们考虑经典的双拷贝,它涉及双伴随标量,规范和引力理论的解决方案。使用最近开发的扭量表达这个想法,我们使用成熟的技术表明,多极矩的任意真空型D重力场直接映射到他们的同行在规范和双伴随标量理论的单和零副本。我们交叉检查我们的结果使用以前获得的克尔度规的结果。我们的研究结果为双拷贝如何运作提供了进一步的物理直观。

英文摘要:

We consider the classical double copy, that relates solutions of biadjoint scalar, gauge and gravity theories. Using a recently developed twistor expression of this idea, we use well-established techniques to show that the multipole moments of arbitrary vacuum type D gravity fields are straightforwardly mapped to their counterparts in gauge and biadjoint scalar theory by the single and zeroth copies. We cross-check our results using previously obtained results for the Kerr metric. Our results provide further physical intuition of how the double copy operates.
