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.

这项研究计划的宏伟目标从提供对现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尺度。换句话说：我们能把引力的精确计算推进多远？它从根本上告诉了我们什么关于引力理论和它与量子世界的解决方案？该计划独特地解决了两个合并的紧凑物体（如黑洞）对引力波形精确理论模板的及时高需求。随着全球范围内引力波探测器网络的迅速发展，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。该计划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，以分析预测这种紧凑双星的引力辐射，并进一步发展量子场论进步的强大用途来研究引力，在那里我发挥了至关重要的作用。从粒子物理学领域到研究引力理论中的基本概念，这种思想和方法的创新发展使我们揭示了深刻的二元关系在规范和引力理论之间，并揭示经典和量子场论的普遍共性。鉴于其深远的目标和其非传统的性质，这个研究计划，它连接传统的物理学的不同分支，具有跨理论和实验物理交叉概念影响的潜力。
