Static Local Field Factor and Ground State Properties of Interacting Electron Gas

Abstract: In the most general case, the calculation of the static local field factor G(q) for the unpolarised electron gas requires the knowledge of exchange--correlation energy functionals for both the parallel and antiparallel relative spin orientations of the electron gas system. Accurate density interpolation formulae using the quantum Monte Carlo data of Ceperley-Alder for the correlation energy of electron gas in both the "para" and "ferro" states, respectively, in the given density range are used for the calculat… Show more

“…The use of appropriate local field factor (LFF) is very important in property calculation of metallic system. Therefore, we have also used most recent Sarkar et al's local field factor (SLFF) [25] based exchange and correlation function in the present investigation. Sarkar et al [25] have recently proposed LFF local field correction function using the quantum Monte Carlo data of Ceperley-Alder for the correlation energy of electron gas in both the "para" and "ferro" states in the given density range.…”
