Title :Application of the Dielectric Formulation to the Multi-Component, Many-Particle System with Coulomb Interaction
Authors :Ginoza, Mitsuaki
Authors alternative :宜野座, 光昭
Issue Date :Mar-1974
Abstract :In terms of a generalized dielectric constant ε (q,ω) defined by Nozieres and Pines, a multi-component, many-particle system with Coulomb interaction is described. By this formulation, various kinds of charged particle systems can be discussed from the unified point of view. ε (q,ω) is calculated in the random phase approximation (R.P.A.). Fermi(F), Bose(B), Bose and Bose(BB), Bose and Fermi(BF), and Fermi and Fermi(FF) systems are discussed. For F, B, BB, and BF, the ε (q,ω) obtained above leads directly to the results of Gell-Mann and Brueckner, Foldy, Bassichis, and Ginoza and Kanazawa, respectively. It is made obvious in this discussion that in the high density limit, the results obtained by treating Bose components by Bogoliubov method are naturally equivalent to those obtained in terms of the R.P.A.
