微正则态和纯态的积分涨落定理

Integral Fluctuation Theorem for Microcanonical and Pure States

Robin Heveling, Jiaozi Wang, Jochen Gemmer

摘要:

基于对跃迁几率的一些自然假设,给出了孤立量子系统的积分涨落定理的一个推导过程。在这些"刚性"和"光滑性"的假设下,对于微正则态和纯量子态,IFT紧随其后。我们数值检查IFT以及我们的假设的有效性,通过分析两个示例性的系统。我们被T告知。Sagawa等人说,他和他的同事发现了可比较的数值结果,并正在准备相应的论文,该论文应与本文在同一天发表。我们建议阅读他们的意见书。

英文摘要:

We present a derivation of the integral fluctuation theorem (IFT) for isolated quantum systems based on some natural assumptions on transition probabilities. Under these assumptions of "stiffness" and "smoothness" the IFT immediately follows for microcanonical and pure quantum states. We numerically check the IFT as well as the validity of our assumptions by analyzing two exemplary systems. We have been informed by T. Sagawa et al. that he and his co-workers found comparable numerical results and are preparing a corresponding paper, which should be available on the same day as the present text. We recommend reading their submission.
