具有相关噪声的速率计算
Rate calculation with correlated noise
摘要:
通常识别反应轨迹计算反应速率需要非常耗时的模拟,特别是如果环境呈现记忆效应。在本文中,我们开发了一种新的方法,允许识别的反应轨迹在一个系统的作用下的随机有色驱动。这种方法是基于作为反应性的分离矩阵的不变结构的微扰计算。此外,使用这种微扰方案,我们已经得到了一个形式上的精确表达式的反应速率在多维系统耦合到有色噪声环境。
英文摘要:
The usual identification of reactive trajectories for the calculation of reaction rates requires very time-consuming simulations, particularly if the environment presents memory effects. In this paper, we develop a new method that permits the identification of reactive trajectories in a system under the action of a stochastic colored driving. This method is based on the perturbative computation of the invariant structures that act as separatrices for reactivity. Furthermore, using this perturbative scheme, we have obtained a formally exact expression for the reaction rate in multidimensional systems coupled to colored noisy environments.
