不存在微观时间可逆性时的涨落比

Fluctuation Ratios in the Absence of Microscopic Time Reversibility

Sven Dorosz, Michel Pleimling

摘要:

我们研究的波动扩散限制的反应系统被赶出他们的定态。使用数值精确的方法,我们调查的波动率在不同的系统,其违反微观时间可逆性的水平。研究一个平衡系统与系统所做的功有关的量,我们观察到在一定条件下,振荡出现在瞬时波动率的指数行为之上。我们认为,这些振荡编码的概率流在状态空间中的属性。

英文摘要:

We study fluctuations in diffusion-limited reaction systems driven out of their stationary state. Using a numerically exact method, we investigate fluctuation ratios in various systems which differ by their level of violation of microscopic time reversibility. Studying a quantity that for an equilibrium system is related to the work done to the system, we observe that under certain conditions oscillations appear on top of an exponential behavior of transient fluctuation ratios. We argue that these oscillations encode properties of the probability currents in state space.
