AI总结:

通过双复制方法,在无全局视界和热谱的背景规范场中,研究霍金辐射的非扰动特性及黑洞时空的统一描述。

摘要:

引力与规范理论通过双复制被具体联系起来。尽管在真空中的扰动散射层面已被深入研究,但关于非扰动特性或超越平凡背景的双复制扩展了解甚少。我们在此展示了如何通过在无全局视界和无热谱的背景规范场中粒子产生的双复制,使坍缩度规中的霍金辐射、其相关热谱以及视界依赖性显现出来。我们的方法结合了世界线和幅度方法,并允许将几种经典和量子双复制预设统一应用于黑洞时空。

英文摘要:

Gravity and gauge theory are concretely linked by the double copy. Although well-studied at the level of perturbative scattering in vacuum, far less is known about non-perturbative aspects or extensions of the double copy beyond trivial backgrounds. We show here how Hawking radiation in a collapse metric, its associated thermal spectrum, and horizon-dependence, emerges from the double copy of particle production in a background gauge field, where there is no global horizon, nor a thermal spectrum. Our approach combines worldline and amplitudes methods, and allows the unification of several classical and quantum double copy prescriptions for black hole spacetimes.
