项目摘要

The grand objectives of this research program extend from delivering analytical high-precision predictionsfor real-world gravitational-wave data, to developing our fundamental understanding of gravity from thesmallest quantum to the largest cosmological scales. In other words: How far and deep can we pushprecision computation in gravity? And what does it fundamentally tell us about gravity theory and itsresolution with the quantum world?This program uniquely addresses the timely high demand for accurate theoretical templates of gravitationalwaveforms from two merging compact objects, such as black holes. Pushing the precision frontier forgravitational waves is one of the most urgent tasks in theoretical physics today, in light of the increasinginflux of data from a rapidly growing worldwide network of gravitational-wave detectors. The programbuilds on my unique expertise in both quantum field theory and gravity to analytically predict gravitationalradiation from such compact binaries, and to further develop the powerful use of quantum field theory advances to study gravity, where I have played a crucial role.This innovative development of ideas and methods from the realm of particle physics to study fundamentalconcepts in gravity theories leads us to uncover profound duality relations between gauge and gravitytheories, and to expose universal commonalities across classical and quantum field theories. In light of itsfar-reaching objectives and its non-traditional nature, this research program, which links traditionallydisparate branches of physics, has a high potential for crossover conceptual impact across theoretical andexperimental physics.

这个研究计划的宏伟目标从提供对真实世界引力波数据的高精度分析预测，到发展我们对引力的基本理解，从最小的量子到最大的宇宙学尺度。换句话说：我们可以在重力领域推动精确计算走多远、走多深？它从根本上告诉了我们什么关于引力理论及其与量子世界的分辨率？这个程序独一无二地解决了对来自两个合并的致密天体(如黑洞)的引力波形的准确理论模板的及时高需求。鉴于来自快速增长的全球引力波探测器网络的越来越多的数据涌入，推动引力波的精确前沿是当今理论物理学最紧迫的任务之一。这个项目建立在我在量子场论和引力方面的独特专业知识的基础上，以解析的方式预测来自这种致密双星的引力辐射，并进一步发展量子场理论的强大功能来研究引力，我在这方面发挥了关键作用。这种从粒子物理领域研究引力理论基本概念的想法和方法的创新发展，使我们揭示了规范理论和引力理论之间深刻的二元性关系，并揭示了经典和量子场论之间的普遍共性。鉴于其深远的目标和非传统的性质，这一研究计划将传统上截然不同的物理学分支联系在一起，具有跨越理论物理和实验物理的交叉概念影响的高潜力。
