圈量子引力研究综述

A Short Review of Loop Quantum Gravity

Abhay Ashtekar, Eugenio Bianchi

摘要:

在我们探索超越爱因斯坦的物理学的过程中,一个悬而未决的问题是广义相对论(GR)和量子物理学的统一。圈量子引力(LQG)是实现这一目标的主要途径。它的核心是GR的核心教训:引力是时空几何的一种表现。因此,这种方法强调几何学的量子性质,并侧重于其在极端情况下的影响-大爆炸附近和黑洞内部-爱因斯坦的光滑连续体破裂。我们提出了一个简短的概述LQG的基本思想,并强调了一些最近的进展。本报告是针对非专家的。

英文摘要:

An outstanding open issue in our quest for physics beyond Einstein is the unification of general relativity (GR) and quantum physics. Loop quantum gravity (LQG) is a leading approach toward this goal. At its heart is the central lesson of GR: Gravity is a manifestation of spacetime geometry. Thus, the approach emphasizes the quantum nature of geometry and focuses on its implications in extreme regimes -- near the big bang and inside black holes -- where Einstein's smooth continuum breaks down. We present a brief overview of the main ideas underlying LQG and highlight a few recent advances. This report is addressed to non-experts.
