论文摘要
在论文中，“时间与时钟：热力学方法” Lucia和Grisolia描述了时间的物理性质与热力学中的宏观不可逆性之间的联系。他们还讨论了通过基于黑体行为的方法来构建热力学时钟的可能性。他们的工作主要集中在宏观的反逆转之上，并且它们定义“热力学时间”的尝试基于非平衡热力学的概念，例如熵产生和时间依赖于时间依赖的热力学通量。在这封信中，我们提出了一种基于莫波尔图伊斯原理的第一原理方法，以描述平衡现象的时间和热力学之间的联系。我们对温度作为功能的新颖解释使我们能够在满足局部平衡假设时将形式主义扩展到不可逆的过程。通过我们的框架，我们还建立了平衡和非平衡时间尺度之间的功能关系，同时区分两者。
In the paper, "Time & clocks: A thermodynamic approach" Lucia and Grisolia describe the connections between the physical nature of time and macroscopic irreversibility in thermodynamics. They also discuss the possibility of constructing a thermodynamic clock that links the two, through an approach based on the behaviour of a black body. Their work primarily focuses on the macroscopic irreversibilty, and their attempt to define 'thermodynamic time' is grounded on the concepts from non-equilibrium thermodynamics such as, entropy generation and time-dependent thermodynamic fluxes - in and out of the system. In this letter, we present a first principles approach based on the Maupertuis principle to describe the connection between time and thermodynamics for equilibrium phenomena. Our novel interpretation of the temperature as a functional allows us to extend our formalism to irreversible processes when the local equilibrium hypothesis is satisfied. Through our framework we also establish a functional relationship between equilibrium and non-equilibrium time-scales while distinguishing between the two.
