First-principles calculation of electronic excitations in solids with SPEX
Arno Schindlmayr, Christoph Friedrich, Ersoy Sasioglu +1
We describe the software package SPEX, which allows first-principles calculations of quasiparticle and collective electronic excitations in solids using techniques from many-body p…
The HSE hybrid functional within the FLAPW method and its application to GdN
Martin Schlipf, Markus Betzinger, Christoph Friedrich +2
We present an implementation of the Heyd-Scuseria-Ernzerhof (HSE) hybrid functional within the full-potential linearized augmented-plane-wave (FLAPW) method. Pivotal to the HSE fun…
Band convergence and linearization error correction of all-electron GW calculations: The extreme case of zinc oxide
Christoph Friedrich, Mathias C. Müller, Stefan Blügel
Recently, Shih et al. [Phys. Rev. Lett. 105, 146401 (2010)] published a theoretical band gap for wurtzite ZnO, calculated with the non-selfconsistent GW approximation, that agreed…
Local exact exchange potentials within the all-electron FLAPW method and a comparison with pseudopotential results
Markus Betzinger, Christoph Friedrich, Stefan Blügel +1
We present a general numerical approach to construct local Kohn-Sham potentials from orbital-dependent functionals within the all-electron full-potential linearized augmented-plane…
