粗粒化条件下非均匀介质中的涨落定理

Fluctuation theorems in inhomogenious media under coarse graining

Sourabh Lahiri, Shubhashis Rana, A. M. Jayannavar

摘要:

当介质摩擦系数与空间有关时,我们比较了欠阻尼和过阻尼系统中功和熵的涨落关系。我们发现,在这两种情况下,这些关系保持不受影响。然而,对于过阻尼系统,分析涉及较多,盲目应用微积分的一般规则会导致不一致的结果。

英文摘要:

We compare the fluctuation relations for work and entropy in underdamped and overdamped systems, when the friction coefficient of the medium is space-dependent. We find that these relations remain unaffected in both cases. However, for the overdamped system, the analysis is more involved, and a blind application of normal rules of calculus would lead to inconsistent results.
