Reichenbach原理背景下的混合、隧道和时间方向
Mixing, tunnelling and the direction of time in the context of Reichenbach's principles
摘要:
本文回顾了Hans Reichenbach对时间方向的理解,包括时间流动与热力学第二定律(即玻尔兹曼时间假设)的基本关系,以及熵增加的平行原理。一个具有量子效应的混合过程的例子,在这里结合赖兴巴赫的思想提出,表明存在一种目前未知的机制,反映了宇宙中普遍存在的全球条件,并在局部制定了时间的方向(即“时间引物”)。实验检测的时间引物的可能性也进行了讨论:如果时间引物是CPT不变的,它的检测可能是在高能量的实验在目前的技术水平。
英文摘要:
This work reviews the understanding of the direction of time introduced by Hans Reichenbach, including the fundamental relation of the perceived flow of time to the second law of thermodynamics (i.e. the Boltzmann time hypothesis), and the principle of parallelism of entropy increase. An example of a mixing process with quantum effects, which is advanced here in conjunction with Reichenbach's ideas, indicates the existence of a presently unknown mechanism that reflects global conditions prevailing in the universe and enacts the direction of time locally (i.e. the "time primer"). The possibility of experimental detection of the time primer is also discussed: if the time primer is CPT-invariant, its detection may be possible in high-energy experiments under the current level of technology.
