具有长程记忆随机系统中的电流涨落

Current fluctuations in stochastic systems with long-range memory

R. J. Harris, H. Touchette

摘要:

提出了一种计算一类具有历史依赖率的随机粒子系统中电流涨落大偏差的方法。长程的时间相关性被认为是改变的速度的大偏差函数在类比与长程的空间相关性在平衡系统。我们给出了一些有启发性的例子,并讨论了Gallavotti-Cohen涨落定理的适用性。

英文摘要:

We propose a method to calculate the large deviations of current fluctuations in a class of stochastic particle systems with history-dependent rates. Long-range temporal correlations are seen to alter the speed of the large deviation function in analogy with long-range spatial correlations in equilibrium systems. We give some illuminating examples and discuss the applicability of the Gallavotti-Cohen fluctuation theorem.
