Abstract: | The accurate theoretical expressions of the mean field operator associated with the multi-configuration time-dependent Hartree-Fock (MCTDHF) method are presented in this paper. By using a theoretical formula, derived without approximation, we can study the multi-electron correlation dynamics accurately. Some illustrative calculations are carried out to check the accuracy of the expression of the mean field operator. The results of illustrative calculations indicate the reliability of the accurate expression of the mean field operator. This theoretical calculation method for the mean field operator may be of considerable help in future studies of the correlated dynamics of many-electron systems in strong laser fields. |
