时间是内在一致性的结果

Time as a Consequence of Internal Coherence

Leandro R. S. Mendes, Diogo O. Soares-Pinto

摘要:

时间是一个难以把握的概念。虽然我们还没有完全理解它,但在如何解释它方面已经取得了一些进展,其中之一就是Page-Wootters机制。在这种机制中,时间被看作是一个不可接近的坐标,时间的明显流逝是全球状态的子系统之间的相关性的结果。在这里,我们提出了一个措施,捕获的机制的关系字符,显示内部的连贯性是必要的成分出现的时间在页面Wootters模型。此外,我们将它与量子热力学的结果联系起来,表明它与量子相干性的可提取功直接相关。

英文摘要:

Time has been an elusive concept to grasp. Although we do not yet understand it properly, there has been advances made in regards to how we can explain it. One such advance is the Page-Wootters mechanism. In this mechanism time is seen as an inaccessible coordinate and the apparently passage of time arises as a consequence of correlations between the subsystems of a global state. Here we propose a measure that captures the relational character of the mechanism, showing that the internal coherence is the necessary ingredient for the emergence of time in the Page-Wootters model. Also, we connect it to results in quantum thermodynamics, showing that it is directly related to the extractable work from quantum coherence.
