在量子宇宙学中使用轨迹

Using Trajectories in Quantum Cosmology

Patrick Peter

摘要:

基于惠勒·德维特方程的量子宇宙学是在引力环境中实现合理量子效应的一种简单方法。在其minisuperspace版本中,其中一个限制注意FLRW度量与一个单一的比例因子和只有几个自由度描述的问题,可以获得精确的解决方案,从而获得充分的知识的波函数。虽然这是处理量子力学系统的通常方法,但在宇宙学框架中,它本质上是毫无意义的。然后,转向轨迹方法提供了一种推导物理后果的有效手段。

英文摘要:

Quantum cosmology based on the Wheeler De Witt equation represents a simple way to implement plausible quantum effects in a gravitational setup. In its minisuperspace version wherein one restricts attention to FLRW metrics with a single scale factor and only a few degrees of freedom describing matter, one can obtain exact solutions and thus acquire full knowledge of the wave function. Although this is the usual way to treat a quantum mechanical system, it turns out however to be essentially meaningless in a cosmological framework. Turning to a trajectory approach then provides an effective means of deriving physical consequences.
