我们提出了一个详细的研究的退相干校正表面跳跃,最近来自精确因式分解的方法。使用相同的初始条件和相同的电子结构方法的从头算多产卵计算被用作三个分子的参考:乙烯,methaniminium阳离子,富烯,其中非绝热动力学如下的光激发。与Granucci-Barrico基于能量的消相干校正和增强的最少开关表面跳跃方案的比较表明,三种消相干校正方法以定性不同的方式对单个轨迹进行操作,但是这些系统的轨迹平均结果是相似的。
We present a detailed study of the decoherence correction to surface hopping that was recently derived from the exact factorization approach. Ab initio multiple spawning calculations that use the same initial conditions and the same electronic structure method are used as a reference for three molecules: ethylene, the methaniminium cation, and fulvene, for which nonadiabatic dynamics follows a photoexcitation. A comparison with the Granucci–Persico energy-based decoherence correction and the augmented fewest-switches surface-hopping scheme shows that the three decoherence-corrected methods operate on individual trajectories in a qualitatively different way, but the results averaged over trajectories are similar for these systems.
