Ab-initio calculation of the effective on-site Coulomb interaction parameters for half-metallic magnets
Ersoy Sasioglu, Iosif Galanakis, Christoph Friedrich +1
Correlation effects play an important role in the electronic structure of half-metallic (HM) magnets. In particular, they give rise to non-quasiparticle states above (or below) the…
GW quasiparticle calculations with spin-orbit coupling for the light actinides
Towfiq Ahmed, R. C. Albers, A. V. Balatsky +2
We report on the importance of GW self-energy corrections for the electronic structure of light actinides in the weak-to-intermediate coupling regime. Our study is based on calcula…
Effect of Local Electron-Electron Correlation in Hydrogen-like Impurities in Ge
H. Sims, E. R. Ylvisaker, E. Şaşıoğlu +3
We have studied the electronic and local magnetic structure of the hydrogen interstitial impurity at the tetrahedral site in diamond-structure Ge, using an empirical tight binding…
Strong magnon softening in tetragonal FeCo compounds
Ersoy Sasioglu, Christoph Friedrich, Stefan Blügel
Magnons play an important role in fast precessional magnetization reversal processes serving as a heat bath for dissipation of the Zeeman energy and thus being responsible for the…
Many-body effects on the Rashba-type spin splitting in bulk bismuth tellurohalides
I. P. Rusinov, I. A. Nechaev, S. V. Eremeev +3
We report on many-body corrections to one-electron energy spectra of bulk bismuth tellurohalides---materials that exhibit a giant Rashba-type spin splitting of the band-gap edge st…
Elimination of the linearization error and improved basis-set convergence within the FLAPW method
Gregor Michalicek, Markus Betzinger, Christoph Friedrich +1
We analyze in detail the error that arises from the linearization in linearized augmented-plane-wave (LAPW) basis functions around predetermined energies and show that it can…
