The dielectric constant of an interacting electron gas

Abstract: Одно из центральных мест в физике твердого тела занимают исследо-вания вырожденной сильно взаимодействующей электронной плазмы металлов, которая играет определяющую роль в формировании основных характеристик металлического кристалла, таких, как его структура, энергия связи, фононный спектр, электромагнитные свойства. Поэтому для создания теории металлического состояния необходимо знать свой-ства электронной плазмы. Задача вычисления свойств взаимодействую-щего электронного газа, сложная сама по себе, в случае … Show more

“…[10,12], the effective interionic potential is calculated, but we take into account an external electrostatic field and use the local field correction not only in the Hubbard form [13] but also in the Ichimaru form [14]. Effects of surface of semi-infinite metal and external electrostatic field on the effective interionic potential are investigated.…”

“…1 the sharp peak at q w 2kF, that is characteristic of almost all the typical local field corrections [3], shows up in G(q) only for small r,; in the region r, x 10 the peak practically completely disappears.…”

“…Note, that in the whole series in [3], where the exchange-correlation effects are taken into account, the dielectric function is introduced in a slightly other manner, where Xo(q, w ) is the Lindhard function and G(q, w ) (do not confuse with the Green function) is called the local field correction. This function is connected with F(q, w ) by the following correlation:…”

“…A calculation of two-particle correlation function and pair effective potential of electron-electron interaction for semi-bounded metal in the jellium model according to the approach proposed in [12,13] is realized in present work. It allows us to use different forms of local field approximations proposed by Hubbard [14], Ichimaru [15] and others, which were used for homogeneous electron gas.…”
