连续信息流热力学

Thermodynamics with continuous information flow

Jordan M. Horowitz, Massimiliano Esposito

摘要:

我们提供了一个统一的热力学形式主义描述的信息传输的自治以及随机热力学描述的非自治系统。我们演示了如何在辅助系统中不断生成信息,然后将其传输到相关系统,该系统可以利用它来为其他不可能的过程提供燃料。事实上,当联合系统满足第二定律时,相关系统的熵平衡被与两个系统之间的互信息率相关的信息项所修改。我们表明,许多重要的结果,以前推导出的非自治麦克斯韦恶魔可以从我们的形式主义和使用循环分解分析在稳态运行的自治系统中的连续信息流。一个模型系统被用来说明我们的研究结果。

英文摘要:

We provide a unified thermodynamic formalism describing information transfers in autonomous as well as nonautonomous systems described by stochastic thermodynamics. We demonstrate how information is continuously generated in an auxiliary system and then transferred to a relevant system that can utilize it to fuel otherwise impossible processes. Indeed, while the joint system satisfies the second law, the entropy balance for the relevant system is modified by an information term related to the mutual information rate between the two systems. We show that many important results previously derived for nonautonomous Maxwell demons can be recovered from our formalism and use a cycle decomposition to analyze the continuous information flow in autonomous systems operating at steady-state. A model system is used to illustrate our findings.
