无遍历热力学

Thermodynamics without ergodicity

V. L. Kulinskii, K. S. Glavatskiy

摘要:

我们表明,基本的热力学关系可以从确定性力学的非遍历系统。这扩展了遍历系统的类似推导,并表明遍历性不应被认为是系统表现出热力学行为的要求。我们的分析强调了绝热不变量在确定性描述中的作用,并加强了力学和热力学之间的联系。特别是,我们认为,宏观热力学行为的系统是由存在不同的时间尺度在其确定性的微观演化。

英文摘要:

We show that fundamental thermodynamic relations can be derived from deterministic mechanics for a non-ergodic system. This extend a similar derivation for ergodic systems and suggests that ergodicity should not be considered as a requirement for a system to exhibit a thermodynamic behavior. Our analysis emphasizes the role of adiabatic invariants in deterministic description and strengthens the link between mechanics and thermodynamics. In particular, we argue that macroscopic thermodynamic behavior of a system is caused by the existence of different time scales in its deterministic microscopic evolution.
