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…
Nonconventional screening of Coulomb interaction in two-dimensional semiconductors and metals: A comprehensive cRPA study of MX2 (M=Mo, W, Nb, Ta; X=S, Se, Te)
Hamid Reza Ramezani, Ersoy Sasioglu, Hanif Hadipour +4
Experimental observations of large exciton binding energies and non-hydrogenic Rydberg series in 2D semiconducting TMDs, along with deviations in plasmon dispersion in 2D metallic…
Optical properties of MoSe monolayer implanted with ultra-low energy Cr ions
Minh N. Bui, Stefan Rost, Manuel Auge +10
The paper explores the optical properties of an exfoliated MoSe monolayer implanted with Cr ions, accelerated to 25 eV. Photoluminescence of the implanted MoSe reveals…
Bulk and surface electronic structure of BiTe from calculations and photoemission experiments
Dmitrii Nabok, Murat Tas, Shotaro Kusaka +6
We present a combined theoretical and experimental study of the electronic structure of stoichiometric BiTe, a natural superlattice of alternating BiTe quintuple la…
