Influence of Pressure on the Structure and Electronic Properties of the Layered Superconductor Y2C2I2

Kyungsoo Ahn, Reinhard K. Kremer, Arndt Simon +3

The structural properties under hydrostatic pressure up to 3 GPa of the layered rare earth carbide halide superconductor Y2C2I2 are studied by neutron powder diffraction at room te…

The disaster of the Nazi-power in science as reflected by some leading journals and scientists in physics - A bibliometric study

Manuel Cardona, Werner Marx

The consequences of the Nazi-power for the scientific process are described qualitatively in various articles and books. However, recent progress in information systems allows a qu…

Band filling and interband scattering effects in MgB: C vs Al doping

Jens Kortus, Oleg V. Dolgov, Reinhard K. Kremer +1

We argue, based on band structure calculations and Eliashberg theory, that the observed decrease of of Al and C doped MgB samples can be understood mainly in terms of a b…

Impurity and correlation effects on transport in one-dimensional quantum wires

T. Enss, V. Meden, S. Andergassen +3

We study transport through a one-dimensional quantum wire of correlated fermions connected to semi-infinite leads. The wire contains either a single impurity or two barriers, the l…

Dispersion of incoherent spectral features in systems with strong electron-phonon coupling

O. Rösch, O. Gunnarsson

We study (inverse) photoemission from systems with strong coupling of doped carriers to phonons. Using an adiabatic approximation, we develop a method for calculating spectra. This…

Constricted Boron Nanotubes

Jens Kunstmann, Alexander Quandt

The recent discovery of pure boron nanotubes raises questions about their detailed atomic structure. Previous simulations predicted tubular structures with smooth or puckered surfa…
