*посылает лучи Имперской магии*
Пиши. если вдруг, мы с Инри немного знаем английский и можем попытаться помочь. Плюс у меня мама часто переводит технические тексты.
Свет мой, это безумно мило, но тут мне никто не поможет) Университетская программа, как раз тех.перевод. А маму твою мне уж совсем совестно трогать) Ну, ради интереса глянь- если заняться нечем) Посмейся и начни мне снова лучи посылать
In the Green function language, the Fock exchange operator in the Hartree-Fock approximation
(HFA) can be written as iGv. We may therefore regard the GWA as a generalization
of the HFA, where the bare Coulomb interaction v is replaced by a screened interaction W.
We may also think of the GWA as a mapping to a polaron problem where the electrons are
coupled to some bosonic excitations (e.g., plasmons) and the parameters in this model are
obtained from first-principles calculations.
The replacement of v by W is an important step in solids where screening effects are
generally rather large relative to exchange, especially in metals. For example, in the electron
gas, within the GWA exchange and correlation are approximately equal in magnitude, to a
large extent cancelling each other, modifying the free-electron dispersion slightly. But also
in molecules, accurate calculations of the excitation spectrum cannot neglect the effects of
correlations or screening. The GWA is physically sound because it is qualitatively correct in
some limiting cases.
