标题: 为什么UKS得到正确的能量用的却是错误的密度 [打印本页] 作者Author: xujian 时间: 2017-1-11 15:40 标题: 为什么UKS得到正确的能量用的却是错误的密度 在看A Chemist's Guide to Density Functional Theory 2ed一书时,关于the unrestricted Kohn-Sham formalism部分,为什么说“unrestricted techniques give qualitatively correct energies but wrong densities, whereas spin-restricted methods show the opposite behavior, that is, they give reasonable densities accompanied by incorrect energies.”请教各位大神,谢谢! 作者Author: sobereva 时间: 2017-1-11 17:19
这种说法我并不赞同,没必要在意。反倒是限制性开壳层两个都不准
