Single-particle spectrum of the degenerate electron gas

II. Numerical results for electrons coupled to plasmons

  • Published:
Physik der kondensierten Materie

Abstract

The single-particle spectrum of an interacting electron gas is investigated in an approximation with electrons coupled to plasmons. Extensive numerical results for the spectral weight function, the momentum distribution function and the density of states are presented over a range of metallic densities.

Résumé

On examine le spectre à une particule d'un gaz d'électrons interagissants, dans le cadre d'une approximation faisant intervenir le couplage des électrons et des plasmons. On présente de nombreux résultats numériques concernant la densité spectrale, la fonction de distribution d'impulsion et la densité d'états dans un certain domaine de densités métalliques.

Zusammenfassung

Das Einteilchenspektrum eines wechselwirkenden Elektronengases wird in einer Näherung untersucht, welche die Kopplung zwischen Elektronen und Plasmonen berücksichtigt. Es werden für einen Bereich von metallischen Dichten umfassende numerische Ergebnisse für die spektrale Gewichtsfunktion, die Impulsverteilungsfunktion und die Zustandsdichte angegeben.
