近日,荷兰格罗宁根大学的Thomas Flöss及其研究团队取得一项新进展。经过不懈努力,他们揭示大质量引力下的非线性电动力学。相关研究成果已于2024年2月23日在国际知名学术期刊《高能物理杂志》上发表。
该研究团队以大质量引力子交换下的光子低能量有效作用为研究对象,这一作用与描述低能量大质量矢量交换的四费米子相互作用相对应。研究人员展示了如何通过积分出一个大质量引力子来导出4D中最普遍的对偶不变矢量相互作用,反之亦然,任何这样的相互作用在大质量引力中都有自然的解释。
此外,他们还证明了Born-Infeld理论的特殊情况,是如何从无鬼dRGT质量引力中最简单的引力子势产生的。

Abstract: As a counterpart to the four-fermion interaction, which describes massive vector exchange at low energies, we investigate the low energy effective action of photons under exchange of a massive graviton. We show how integrating out a massive graviton leads to the most general duality-invariant vector interactions in 4D or, vice versa, how any such interactions have a natural interpretation within massive gravity. Moreover, we demonstrate how the special case of Born-Infeld theory arises from arguably the simplest graviton potential within ghost-free dRGT massive gravity.
