随机介质中零均值非对称零程过程的大偏差

Large deviations for a zero mean asymmetric zero range process in random media

A. Koukkous, H. Guiol

摘要:

本文考虑无限体积中从平衡点出发具有零平均和随机跳率的非对称零程过程。我们调查的大偏差从流体力学极限的粒子的经验分布,并证明了一个上限和下限的大偏差原则。我们的主要论点是基于无限体积的超指数估计。为此,我们将Kipnis & al.(1989)和Benois & al.(1995)提出的方法推广到我们的情况。

英文摘要:

We consider an asymmetric zero range process in infinite volume with zero mean and random jump rates starting from equilibrium. We investigate the large deviations from the hydrodynamical limit of the empirical distribution of particles and prove an upper and a lower bound for the large deviation principle. Our main argument is based on a super-exponential estimate in infinite volume. For this we extend to our case a method developed by Kipnis & al. (1989) and Benois & al. (1995).
