8.4 Wannier functions

There are several Wannier-related utilities in PostProc:

  1. The "Poor Man Wannier" code pmw.x, to be used in conjunction with DFT+U calculations (see Example 25)
  2. The interface with Wannier90 code, pw2wannier.x: see the documentation in W90/ (you have to install the Wannier90 plug-in)
  3. The wannier_ham.x code generates a model Hamiltonian in Wannier functions basis: see examples/WannierHam_example/.
