WIEN2WANNIER is an interface program between WIEN2k, öffnet eine externe URL in einem neuen Fenster and Wannier90, öffnet eine externe URL in einem neuen Fenster to obtain maximally localized Wannier functions from WIEN2k calculations. It was written by J. Kuneš, P. Wissgott, and E. Assmann.

WIEN2WANNIER 1.0 is included in the WIEN2k_14.2 distribution; to use it, simply install the latest WIEN2k version. WIEN2WANNIER-specific documentation is included in SRC_w2w/.

Changes from v. 0.97 include:

  • WIEN2k integration
    •  (most) wien2wannier programs can be called through x
    • installation in existing WIEN2k directory
  • write_inwf replaces write_w2win and brings new features, e.g.
    • it knows about the real-valued spherical harmonics (s through f), s/p/d hybrids, and certain symmetry-related groups (e.g. d-t2g)
    • an arbitrary rotation can be applied to each initial projection
    • tab-completion, readline and history support
  • fix handling of k-points for all lattice types
  • w2w sets the Fermi energy to zero (i.e. shift_energy is no longer part of the standard procedure)

Caveat:

woptic has been removed from this package and is available here, öffnet in einem neuen Fenster.
