从广义相对论到量子引力

From General Relativity to Quantum Gravity

Abhay Ashtekar, Martin Reuter, Carlo Rovelli

摘要:

在广义相对论(GR)中,时空几何不再只是一个背景领域,而是一个具有自身自由度的物理和动力学实体。我们提出了一个概述的方法,量子引力在GR的这个中心特征是在最前沿。然而,量子理论中的短程动力学与广义相对论中的短程动力学有很大的不同,经典时空和引力子只在一个合适的极限内出现。我们的重点是沟通的关键战略,主要成果和开放的问题。本着本书的精神,我们将重点关注在过去20 - 30年中取得最重大进展的几条途径。

英文摘要:

In general relativity (GR), spacetime geometry is no longer just a background arena but a physical and dynamical entity with its own degrees of freedom. We present an overview of approaches to quantum gravity in which this central feature of GR is at the forefront. However, the short distance dynamics in the quantum theory are quite different from those of GR and classical spacetimes and gravitons emerge only in a suitable limit. Our emphasis is on communicating the key strategies, the main results and open issues. In the spirit of this volume, we focus on a few avenues that have led to the most significant advances over the past 2-3 decades.
