Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten

open access: yesphysica status solidi (b), EarlyView.
This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

Propagation of Electromagnetic Waves in Optically Anisotropic Materials: Polarization and Intensity Behavior

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
The polarization change of an arbitrarily polarized wave in an optically anisotropic medium is discussed, focusing on cases where the refractive index, the extinction coefficient, and the two eigenmodes are degenerated. The polarization converges to that of the eigenmode with the lowest extinction coefficient, except when the extinction coefficients ...

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.

An Extended Hückel Theory Parameter Set for Efficient Electronic Structure Calculations of SiGe Alloys

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
A new parameterization of Si and Ge in the framework of the extended Hückel theory is presented. Bandgap and effective mass are calculated for unstrained and biaxially strained SiGe alloys. In SiGeC alloys with C atoms in close proximity, additional bands are observed, which are related to defect states in real crystals.

Vortex Ratchet Effect in Superconductor Open Nanotubes and 3D Nanoflakes

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
Magnetic flux quanta in 3D superconductor nanotubes move in the regions where the normal component of the applied magnetic field is close to maximum. Asymmetric pinning sites placed in these areas result in an enhanced vortex ratchet effect compared to planar systems.

Kriging‐variance‐based multi‐member ensembles of radar–rain‐gauge precipitation estimates: Application in Switzerland

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We explore the variance of the radar–rain‐gauge combination kriging‐based system “CombiPrecip”, showing that it represents satisfactorily the radar–rain‐gauge precipitation uncertainty around the kriging expected value. We then present a method to generate ensembles out of it, which we find to be very similar in texture with the expected‐value image ...
