基于块相关框架的多参考微扰理论和多参考耦合簇理论
Multireference Perturbation Theory and Multireference Coupled Cluster Theory Based on the "Block-Correlation" Framework
摘要
Abstract
Well-developed conventional single-reference electron-correlation methods usually fail to describe the dissociation of covalent bonds,di(or poly)radical systems or electronic structures of the excited states.Based on a multi-determinantal wave function,recently emerged multireference perturbation theories and coupled cluster theories can give drastically improved results;however,there is still no satisfactory scheme so far.In this monograph,alternative multireference perturbation theories and coupled cluster theories based on the "block-correlation" framework has been introduced and illustrated in detail,together with proper comparisons with other common electron-correlation methods.Future perspectives upon multireference theories have also been briefly discussed.关键词
