Thin-film effects on the surface stopping power of a free electron gas
A. Garcia-Lekue, J. M. Pitarke
The electronic properties of thin films present quantum-size effects, which are a consequence of the finite size of the system. Here we focus on the investigation of these effects…
Recent Progress in the Computational Many-Body Theory of Metal Surfaces
M. Nekovee, J. M. Pitarke
In this article we describe recent progress in the computational many-body theory of metal surfaces, and focus on current techniques beyond the local-density approximation of densi…
Electronic response of aligned multishell carbon nanotubes
J. M. Pitarke, F. J. Garcia-Vidal
We report calculations of the effective electronic response of aligned multishell carbon nanotubes. A local graphite-like dielectric tensor is assigned to every point of the multis…
Jellium surface energy beyond the local-density approximation: Self-consistent-field calculations
J. M. Pitarke, A. G. Eguiluz
We report extensive self-consistent calculations of jellium surface energies, by going beyond the local-density approximation. The density-response function of a bounded free-elect…
Surface-state electron dynamics in noble metals
P. M. Echenique, J. Osma, M. Machado +3
Theoretical investigations of surface-state electron dynamics in noble metals are reported. The dynamically screened interaction is computed, within many-body theory, by going beyo…
Metallic slabs: Perturbative treatments based on jellium
C. Fiolhais, C. Henriques, I. Sarria +1
We examine first-order perturbative results based on jellium for the surface energy of slabs of simple metals, using various local pseudopotentials (Ashcroft, Heine-Abarenkov and e…
