作为Gibbs性质的涨落定理

The Fluctuation Theorem as a Gibbs Property

Christian Maes

摘要:

最近的研究利用动力系统和非平衡统计力学之间的关系的共同点是,所以我们认为,标准的吉布斯形式主义的水平上应用的时空历史。假设(混沌性原理)的基础上的Gallavotti-Cohen波动定理,使之成为可能,使用符号动力学,采用一维晶格自旋系统的理论。Kurchan和Lebowitz-Spohn对随机动力学涨落定理的分析可以在时空测度的水平上重述,时空测度是由跃迁概率决定的相互作用的吉布斯测度。在本文中,我们把涨落定理理解为吉布斯性质,因为它是从吉布斯态的定义出发的。我们给出了一个本地版本的波动定理在吉布斯的上下文中,我们从这个版本也为一些类的空间扩展的随机动力学。

英文摘要:

Common ground to recent studies exploiting relations between dynamical systems and non-equilibrium statistical mechanics is, so we argue, the standard Gibbs formalism applied on the level of space-time histories. The assumptions (chaoticity principle) underlying the Gallavotti-Cohen fluctuation theorem make it possible, using symbolic dynamics, to employ the theory of one-dimensional lattice spin systems. The Kurchan and Lebowitz-Spohn analysis of this fluctuation theorem for stochastic dynamics can be restated on the level of the space-time measure which is a Gibbs measure for an interaction determined by the transition probabilities. In this note we understand the fluctuation theorem as a Gibbs property as it follows from the very definition of Gibbs state. We give a local version of the fluctuation theorem in the Gibbsian context and we derive from this a version also for some class of spatially extended stochastic dynamics.
