A novel valence-bond-based automatic diabatization method by compression, called valence-bond-based compression approach for dibatization (VBCAD), is presented in this Letter. It is a “black-box” type method that provides an automatic diabatization from a classical valence bond (VB) perspective. In VBCAD, a model space projection is performed by an eigenvalue decomposition algorithm followed by dimensional reduction based on a sequence of Householder transformations. Our diabaticity criterion is implemented in a way that maximizes the diversity of VB structure weights between different diabatic states. Owing to the rigorous Householder transformations employed in this entire procedure, the invariance of the target eigensubspace is preserved. This is illustrated on two prototypical examples.

一种新的基于价键的压缩自动绝热方法。

在这封信中,提出了一种新颖的基于价键的压缩自动绝热方法,称为基于价键的二值化压缩方法(VBCAD)。这是一种“黑匣子”类型的方法,从经典的价键(VB)角度提供自动的绝热。在VBCAD中,模型空间投影由特征值分解算法执行,然后基于一系列Householderer变换进行降维。我们的非绝热性标准以最大化不同非绝热状态之间VB结构权重多样性的方式实施。由于在整个过程中采用了严格的Householder变换,因此保留了目标特征子空间的不变性。这在两个原型示例中得到了说明。
