The Effective Electron-Positron Potential in Jellium

Electron Correlations in Local Effective Potential Theory

Local effective potential theory, both stationary-state and time-dependent, constitutes the mapping from a system of electrons in an external field to one of the noninteracting fermions possessing the same basic variable such as the density, thereby enabling the determination of the energy and other properties of the electronic system. This paper is a description via Quantal Density Functional ...

Density Functional Theory for the Electron Gas and for Jellium

J. W. Dufty1 1Department of Physics, University of Florida, Gainesville, FL 32611 (Dated: April 26, 2017) Abstract Density Functional Theory relies on universal functionals characteristic of a given system. Those functionals in general are di¤erent for the electron gas and for jellium (electron gas with uniform background). However, jellium is frequently used to construct approximate functional...

Exact exchange optimized effective potential and self-compression of stabilized jellium clusters

In this work, we have used the exchange-only optimized effective potential in the self-consistent calculations of the density functional Kohn-Sham equations for simple metal clusters in stabilized jellium model with self-compression. The results for the closed-shell clusters of Al, Li, Na, K, and Cs with N =2, 8, 18, 20, 34, and 40 show that the clusters are 3% more compressed here than in the ...

Pumping Electron-Positron Pairs from a Well Potential.

In the presence of very deep well potential, electrons will spontaneously occupy the empty embedded bound states and electron-positron pairs are created by means of a non-perturbative tunneling process. In this work, by slowly oscillating the width or depth, the population transfer channels are opened and closed periodically. We find and clearly show that by the non-synchronous ejections of par...
