球对称量子引力中的量子标量场

Revisiting the quantum scalar field in spherically symmetric quantum gravity

Enrique F. Borja, Iñaki Garay, Eckhard Strobel

摘要:

在圈量子引力框架下,我们推广了球对称引力系统与无质量标量场耦合的结果。我们以史瓦西时空为出发点。这里给出的结果依赖于统一离散化方法。我们能够使用变分法最小化相关的离散主约束。真空的试验状态由物质部分的Fock真空和以经典史瓦西解为中心的高斯真空的直积组成。本文遵循Gambini,Pullin和Rastgoo提出的研究路线,并将他们的结果与本文给出的结果作了比较。

英文摘要:

We extend previous results in spherically symmetric gravitational systems coupled with a massless scalar field within the loop quantum gravity framework. As starting point, we take the Schwarzschild spacetime. The results presented here rely on the uniform discretization method. We are able to minimize the associated discrete master constraint using a variational method. The trial state for the vacuum consists of a direct product of a Fock vacuum for the matter part and a Gaussian centered around the classical Schwarzschild solution. This paper follows the line of research presented by Gambini, Pullin and Rastgoo and a comparison between their result and the one given in this work is made.
