非平衡随机系统中的热过程

Heat processes in non-equilibrium stochastic systems

Jiří Pešek

摘要:

本文致力于非平衡随机系统中慢热力学过程的理论研究。其主要结果是一个物理和数学上一致的建设有关的热力学量在准静态极限的一大类非平衡模型。作为一般方法的一个应用,本文介绍了热容的自然非平衡推广,并详细分析了它的性质,包括一种反常的远离平衡的行为。所开发的方法被进一步应用到时间尺度分离的相关问题,在那里它们能够以更精确的方式描述慢和快自由度的有效动态。

英文摘要:

This thesis is devoted to the theoretical study of slow thermodynamic processes in non-equilibrium stochastic systems. Its main result is a physically and mathematically consistent construction of relevant thermodynamic quantities in the quasistatic limit for a large class of non-equilibrium models. As an application of general methods a natural non-equilibrium generalization of heat capacity is introduced and its properties are analyzed in detail, including an anomalous far-from-equilibrium behavior. The developed methods are further applied to the related problem of time-scale separation where they enable to describe the effective dynamics of both slow and fast degrees of freedom in a more precise way.
