Efficient all-electron Bethe-Salpeter implementation using crystal symmetries
Jörn Stöhler, Stefan Blügel, Christoph Friedrich
We describe an all-electron implementation of the Bethe-Salpeter equation (BSE) for the calculation of optical absorption spectra in the full-potential linearized augmented-plane-w…

Implementation and application of a DFT approach within the all-electron FLAPW method
Wejdan Beida, Gustav Bihlmayer, Christoph Friedrich +3
We present an implementation of the density-functional theory DFT formalism within the all-electron full-potential linearized augmented-plane-wave (FLAPW) method as impleme…

Chiral split magnons in metallic g-wave altermagnets: Insights from many-body perturbation theory
Wejdan Beida, Ersoy Sasioglu, Christoph Friedrich +3
Altermagnets are a novel class of magnetic materials that bridge the gap between ferromagnets (FMs) and antiferromagnets (AFMs). A key feature is the non-degeneracy of magnon modes…
