Abstract
We study the linear response of a two-state stochastic process, obeying the renewal condition, by means of a stochastic rate equation equivalent to a master equation with infinite memory. We show that the condition of perennial aging makes the response to coherent perturbation vanish in the long-time limit.
摘要
我们通过一个与具有无限记忆的主方程等效的随机速率方程，研究了一个服从更新条件的两态随机过程的线性响应。我们表明，长期老化的条件使得在长时间极限下对相干微扰的响应消失。
