Barrierless electronic relaxation in solution -- two state model with exact analytical solution in time domain

Aniruddha Chakraborty

摘要:

我们提出了一种解析方法来解决电子弛豫问题的解决方案在时域中,模拟的粒子进行扩散的影响下的两个耦合的潜力。假设两个势之间的耦合由任意位置和强度的狄拉克δ函数表示。用Smoluchowskii方程模拟两种势面上的扩散运动。本文给出了生存概率的时域解析表达式。这是第一次在时域上得到解析解,该方法也可用于求解其它势函数问题。

英文摘要:

We propose an analytical method for solving the problem of electronic relaxation in solution in time domain, modelled by a particle undergoing diffusion under the influence of two coupled potentials. The coupling between the two potentials is assumed to be represented by a Dirac delta function of arbitrary position and strength. Smoluchowskii equation is used model the diffusion motion on both the potentials. We report an analytical expression for survival probability in time domain. This is the first time analytical solution in time domain is derived and this method can be used to solve problems involving other potentials.
