Calculations of ground-state and excited-state properties of materials have been one of the
major goals of condensed matter physics. Ground-state properties of solids have been …

Electron dynamics in the bulk and at the surface of solid materials are well known to play a
key role in a variety of physical and chemical phenomena. In this article we describe the …

The dependence of the inelastic lifetime of electrons in the image-potential states of Cu
(100) on their momentum parallel to the surface has been studied experimentally by means …

Materials where electrons show nearly localized rather than itinerant behaviour, such as the
high-temperature superconducting copper oxides, or manganate oxides, are attracting …

Catalytic methylation utilising methanol as a sustainable C1 building block and hydrogen
source continues to attract attention due to its atom-economical, cost-effective, and simple …

The unequivocal observation in the early 1980s of a new class of unoccupied surface states
that are bound to the vacuum level of a variety of metal surfaces has led over the last two …

The dynamics of excited electronic states at Ag surfaces is studied by evaluating the
quasiparticle self-energy within the GW approximation. The screened Coulomb interaction …

The many-body GW approximation has become the most popular method in ab initio
calculations of excited-state properties in real materials. GW overcomes many of the …

After the early suggestion by John Pendry (1980 Phys. Rev. Lett. 45 1356) to probe
unoccupied bands at surfaces through the time reversal of the photoemission process, the …

First principles calculations of bandstructures of crystals are usually based on one-particle
theories where the electrons are assumed to move in some effective potential. The most …
