开放量子系统中不可逆性的表征

Characterizing irreversibility in open quantum systems

T. B. Batalhao, S. Gherardini, J. P. Santos, G. T. Landi, M. Paternostro

摘要:

不可逆转性是一个基本概念,在许多层面具有重要影响。它指出了内在可逆的微观运动方程和宏观水平上出现的单向时间箭头之间的根本区别。更务实的是,一个给定过程的不可逆性程度的完全量化可以帮助描述在量子水平上运行的热机的性能。在这里,我们回顾了熵产生的概念,这是通常打算作为{ \it的}措施的热力学不可逆性的过程中,查明其目前制定的特点和缺点。

英文摘要:

Irreversibility is a fundamental concept with important implications at many levels. It pinpoints the fundamental difference between the intrinsically reversible microscopic equations of motion and the unidirectional arrow of time that emerges at the macroscopic level. More pragmatically, a full quantification of the degree of irreversibility of a given process can help in the characterisation of the performance of thermo-machines operating at the quantum level. Here, we review the concept of entropy production, which is commonly intended as {\it the} measure of thermodynamic irreversibility of a process, pinpointing the features and shortcomings of its current formulation.
