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.

Uncovering the Drivers of the Equatorial Ocean Surface Winds

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Wind Patterns along the Equator. Shown are daily mean wind patterns along the equatorial basin indicated in Figure 1a as a meridional mean along −2∘$$ -{2}^{\circ } $$ to +2∘$$ +{2}^{\circ } $$ latitude, land cells included, from a 2‐year ICON simulation. Five ocean basins are shown in black. Yellow boxes outline the seasons and ocean basins, which are

Latent data assimilation with non‐explicit observation operator in hydrology

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We design a latent neural mapping in the form of a neural network and integrate this within data assimilation. The resulting approach helps mitigate computational costs while addressing the problem of local corrections due to sparse observations and the lack of an observation operator.
