论文摘要
用于计算系统上的热力学工作的两个点测量方案,要求它最初处于平衡状态。 Margenau-hill方案除其他外观,扩展了先前的方法,以实现非平衡的初始状态。我们根据$ l_1 $ - coherence措施量化了两个方案之间的定量比较。我们表明,可以根据这种初始连贯性来施放两个方案中两个工作的差异,工作差异和平均熵产生之间的差异。此外,我们证明,在Margenau-Hill框架中,平均熵产生可以承受负值。
The Two Point Measurement scheme for computing the thermodynamic work performed on a system requires it to be initially in equilibrium. The Margenau-Hill scheme, among others, extends the previous approach to allow for a non-equilibrium initial state. We establish a quantitative comparison between both schemes in terms of the amount of coherence present in the initial state of the system, as quantified by the $l_1$-coherence measure. We show that the difference between the two first moments of work, the variances of work and the average entropy production obtained in both schemes can be cast in terms of such initial coherence. Moreover, we prove that the average entropy production can take negative values in the Margenau-Hill framework.
