协变因果集上的曲率与量子力学

Curvature and Quantum Mechanics on Covariant Causal Sets

Stanley Gudder

摘要:

本文首先回顾了离散量子引力中的因果集方法。在我们的版本中,这种方法的一个特殊的作用是由协变因果集,我们称之为$c$ -causets。$c$ -causets的重要性在于它们支持离散设置中的自然距离函数、测地线和曲率的概念。然后我们更详细地讨论曲率。通过考虑具有最大和最小路径数的$c$ -原因,我们能够找到具有大和小平均曲率的$c$ -原因。然后,我们简要地讨论了我们以前的工作时,曲率基本为零的暴胀时期。量子力学对$c$ -causets考虑下。本文首先介绍了$c$ -原因的自由波方程。然后,我们展示了如何与一个特定的质量(或能量)的粒子的状态可以从波动方程。它是证明了小的例子,量子力学预测,粒子倾向于向具有较大曲率的顶点移动。

英文摘要:

This article begins by reviewing the causal set approach in discrete quantum gravity. In our version of this approach a special role is played by covariant causal sets which we call $c$-causets. The importance of $c$-causets is that they support the concepts of a natural distance function, geodesics and curvature in a discrete setting. We then discuss curvature in more detail. By considering $c$-causets with a maximum and minimum number of paths, we are able to find $c$-causets with large and small average curvature. We then briefly discuss our previous work on the inflationary period when the curvature was essentially zero. Quantum mechanics on $c$-causets is considered next. We first introduce a free wave equation for $c$-causets. We then show how the state of a particle with a specified mass (or energy) can be derived from the wave equation. It is demonstrated for small examples that quantum mechanics predicts that particles tend to move toward vertices with larger curvature.
