一般跳过程的一个广义积分涨落定理

A generalized integral fluctuation theorem for general jump processes

Fei Liu, Yu-Pin Luo, Ming-Chang Huang, Zhong-can Ou-Yang

摘要:

利用Feynman-Kac和Cameron-Martin-Girsanov公式,通过构造一个时不变的内积,得到了离散跳跃过程的一个广义积分涨落定理.现有的离散IFTs可以作为其具体情况导出。我们的方法和传统的时间反演方法之间的连接也被建立。与现有文献中广泛采用的后一种方法不同,我们的方法可以自然地给出马尔可夫随机系统的时间反演的定义。此外,我们发现鲁棒GIFT通常不会导致详细的波动定理。

英文摘要:

Using the Feynman-Kac and Cameron-Martin-Girsanov formulas, we obtain a generalized integral fluctuation theorem (GIFT) for discrete jump processes by constructing a time-invariable inner product. The existing discrete IFTs can be derived as its specific cases. A connection between our approach and the conventional time-reversal method is also established. Different from the latter approach that was extensively employed in existing literature, our approach can naturally bring out the definition of a time-reversal of a Markovian stochastic system. Additionally, we find the robust GIFT usually does not result into a detailed fluctuation theorem.
