论文摘要
在此白皮书中，我描述了有效野外理论（EFT）技术对经典和量子重力的现代应用，与天体物理学和宇宙学的问题有关。与EFT到高能，核或凝结物理物理学的应用一样，基于重新归一化组的短距离尺度基于短距离尺度的脱钩的威尔逊范式在重力背景下仍然是一个强大的组织原理。然而，时空几何形状的存在带来了新元素（非平凡的时间依赖性，宇宙学或黑洞事件范围），这些元素通常需要在EFT在能量和强度边界的物理学上应用于物理学的应用中引入新的领域理论方法。在简要介绍了将EFT方法应用于重力方面的最新发展之后，我将重点介绍对紧凑型二进制动力学的EFT描述，包括概述了其在Ligo/处女座和其他观测值的重力波检测中实验程序中的某些应用。
In this whitepaper, I describe modern applications of effective field theory (EFT) techniques to classical and quantum gravity, with relevance to problems in astrophysics and cosmology. As in applications of EFT to high-energy, nuclear, or condensed matter physics, the Wilsonian paradigm based on decoupling of short distance scales via renormalization group evolution remains a powerful organizing principle in the context of gravity. However, the presence of spacetime geometry brings in new elements ( non-trivial time-dependence, cosmological or black hole event horizons) which necessitate the introduction of novel field theoretic methods not usually encountered in applications of EFTs to physics at the energy and intensity frontiers. After a brief overview of recent developments in the application of EFT methods to gravity, I will focus on the EFT description of compact binary dynamics, including an overview of some of its applications to the experimental program in gravitational wave detection at LIGO/VIRGO and other observatories.
