Wien2k is a robust code for electronic structure calculations. It is based on density functional theory within a full-potential linearized augmented plane wave (FLAPW) + localized orbitals (lo) method. This is a semi-commercial code, however the CNF has a site license that allows users to take advantage of this package on the CNF cluster.
- Energy bands and density of states
- Total energy, forces, and equilibrium geometries
- electric field graidients, hyperfine fields, isomer shifts
- spin polarized calculations (ferromagnetic or antiferromagnetic)
- spin-orbit coupling
- optical properties
- x-ray emission and absorption spectra, electron energy loss spectra (EELs)
- fermi surfaces
- LDA, GGA, meta-GGA, LDA+U, orbital polarization
Wien2k development is done primarily at the Institute for Materials Chemistry, Technishche Universitat Wien, Austria. The main developers are:
- P. Blaha, K. Schwarz, G. Madsen, D. Kvasnicka, and J. Luitz.
