热力学第二定律概率违背的有限时间界限

Harry J. D. Miller, Martí Perarnau-Llobet

AI总结:

本文针对热马尔可夫环境中的驱动系统,利用热力学长度推导出违背热力学第二定律概率的有限时间界限,并证明其收敛到Jarzynski界限的速率慢于$1/\sqrtτ$,揭示了热力学几何与功的高阶统计性质之间的联系。

摘要:

Jarzynski等式为通过提取超过自由能差值的功而违背热力学第二定律的概率设定了一个强界限。我们针对与热马尔可夫环境接触的驱动系统,推导出该界限的有限时间细化形式,该形式可用热力学长度的几何概念表示。我们证明,有限时间协议以慢于$1/\sqrtτ$的速率收敛到Jarzynski界限,其中$τ$是功提取协议的总时间。我们的结果凸显了最小耗散过程的一种新应用,并展示了热力学几何与功的高阶统计性质之间的联系。

英文摘要:

Jarzynski's equality sets a strong bound on the probability of violating the second law of thermodynamics by extracting work beyond the free energy difference. We derive finite-time refinements to this bound for driven systems in contact with a thermal Markovian environment, which can be expressed in terms of the geometric notion of thermodynamic length. We show that finite-time protocols converge to Jarzynski's bound at a rate slower than $1/\sqrtτ$, where $τ$ is the total time of the work-extraction protocol. Our result highlights a new application of minimal dissipation processes and demonstrates a connection between thermodynamic geometry and the higher order statistical properties of work.
