为什么双激发决定簇支配电子关联的组态相互作用计算
Why doubly excited determinants govern configuration interaction calculations of electron correlations
摘要:
计算证据表明,当使用自然轨道来研究(动态和非动态)电子关联时,具有奇数个激发的行列式起着可以忽略不计的作用。相反,双激发决定因素规则的讲坛,在这种配置相互作用的计算。我们从数学上解释为什么一定是这样。
英文摘要:
Computational evidence shows that, when using natural orbitals to study (dynamical and non-dynamical) electron correlation, determinants with an odd number of excitations play a negligible role. Instead, doubly excited determinants rule the rostrum in this kind of configuration interaction calculations. We explain mathematically why it must be so.
