本文研究了一种非对称谷脊点(VRI)势,其能量面(PES)具有两个连续的指数-1鞍座(上鞍座和下鞍座),其中一个鞍座的能量高于另一个鞍座,两个势阱被下指数-1鞍座隔开。我们展示了当我们修改控制不对称的参数时,势能的深度和平坦度是如何变化的,以及当我们修改相同的参数时,分支比率(进入每口井的轨迹的比率)是如何变化的,以及它与叶的面积的相关性,因为它们是由从LD标量场的梯度中提取的稳定和不稳定流形形成的。
In this paper we study an asymmetric valley-ridge inflection point (VRI) potential, whose energy surface (PES) features two sequential index-1 saddles (the upper and the lower), with one saddle having higher energy than the other, and two potential wells separated by the lower index-1 saddle. We show how the depth and the flatness of our potential changes as we modify the parameter that controls the asymmetry as well as how the branching ratio (ratio of the trajectories that enter each well) is changing as we modify the same parameter and its correlation with the area of the lobes as they have been formed by the stable and unstable manifolds that have been extracted from the gradient of the LD scalar fields.
