"时间从量子引力中出现“与”量子力学中波函数的动力学坍缩“之间的联系

The connection between `emergence of time from quantum gravity' and `dynamical collapse of the wave-function in quantum mechanics'

T. P. Singh

摘要:

有各种理由相信量子理论可能是一种涌现现象。迹动力学是一种基本的非对易矩阵的经典动力学,量子理论和经典力学都是在热力学近似下产生的。然而,在量子理论中用来描述演化的时间是一个外部经典时间,反过来又被认为是一个涌现的特征--一个量子引力基础理论的遗迹。在这篇文章中,我们借用迹动力学的思想来说明经典时间是量子引力物理中算符时间的热力学近似。这一预测将通过正在进行的试图构建宏观物体叠加态的实验室实验来检验。

英文摘要:

There are various reasons to believe that quantum theory could be an emergent phenomenon. Trace Dynamics is an underlying classical dynamics of non-commuting matrices, from which quantum theory and classical mechanics have been shown to emerge, in the thermodynamic approximation. However, the time that is used to describe evolution in quantum theory is an external classical time, and is in turn expected to be an emergent feature - a relic of an underlying theory of quantum gravity. In this essay we borrow ideas from Trace Dynamics to show that classical time is a thermodynamic approximation to an operator time in quantum gravitational physics. This prediction will be put to test by ongoing laboratory experiments attempting to construct superposed states of macroscopic objects.
