引力常量的量子修正

Quantum correction of gravitational constant

Yu-Jie Chen, Shi-Lin Li, Yu-Zhu Chen, Wen-Du Li, Wu-Sheng Dai

摘要:

我们提出了一个考虑引力常量量子修正的方案。在该模型中,引力常量来源于引力场与标量场的耦合。在本文中,我们证明了如果标量场是一个量子场,那么引力常量将有一个依赖于时空的量子修正,使得量子修正后的物理常数不再是一个常数。引力常量的量子修正在不同的时空中是不同的。我们计算了Schwarzschild时空、$H_{3}$(欧几里德$AdS_{3}$)时空、$H_{3}/Z$时空、宇宙模型、de Sitter时空和Rindler时空中的量子修正。

英文摘要:

We suggest a scheme for considering the quantum correction of the gravitational constant. In the model, the gravitational constant originates from a coupling of the gravitational field with a scalar field. In this paper, we show that if the scalar field, as it should be in the real physical world, is a quantum field, then the gravitational constant will have a spacetime-dependent quantum correction, so that the quantum corrected physical constant is no longer a constant. The quantum correction of the gravitational constant is different in different spacetime. We calculate the quantum correction in the Schwarzschild spacetime, the $H_{3}$ (Euclidean $AdS_{3}$) spacetime, the $H_{3}/Z$ spacetime, the universe model, the de Sitter spacetime, and the Rindler spacetime.
