Construction of first-principles density functional approximations and their applications to materials
… are fitted to paradigmatic metallic systems: jellium surfaces and closed-shell jellium clusters. Last, we modify an exchange-correlation kernel that describes the density-density response of jellium to better satisfy known frequency sum rules. We also constrain the kernel to reproduce the …

Photoelektronenspektroskopie massenselektierter Aluminium-, Silizium- und Natriumcluster
… Metallcluster werden dabei die Vorhersagen des Jellium-Modells untersucht; allgemein werden Ausagen bezüglich der geometrischen Struktur der Cluster überprüft. Bei den Siliziumclustern wird die Entwicklung der Energielücke verfolgt. Da im Fall von Aluminium in einem großen <br>Massenbereich …

Computational Study of Carbon-Based Low-Dimensional Materials on Structures, Properties and Applications
… reduction of CO2. Lastly, the simplified model- jellium model- has been applied in carbon nanotube growth. The termination effect and the chiral selectivity in CNT growth have been investigated.

Optical Response Of Finite And Extended Systems
… hole pairs on the static local field factor of jellium with and without a gap, using the Bethe-Salpeter equation. We only considered diagrams where the electron hole pair interact, via a statically screened Coulomb interaction, and we summed these diagrams to infinite order. First we coupled …

Photoemission studies of surfaces and thin film systems of silver and gold
… greater than what is expected from a jellium calculation. This result implies that significant subsurface-core-level shifts can occur for close-packed metal surfaces. For the studies of the zone center surface state of Au overlayers on Ag(lll), it was observed that this surface state …

Spin-Orbit Delays in Photoemission from Bi2Te3 and Bi2Se3
… Schrödinger equation for photoemission in Jellium-type model including electron-hole interaction and IR field penetration that photoelectron transport cannot account for the experimentally observed delays. Instead, calculations indicate that RABBITT can probe large Eisenbud-Wigner-Smith …

Application of quantum Monte Carlo methods to homogeneous electron and electron-hole systems
The properties of the macroscopic world around us, and of which we are a part, are largely determined by the low energy, collective behaviour of many interacting particles, including the nuclei and, especially, the electrons present. Although the fundamental laws governing the behaviour of these …
