WebWannier functions (WFs) can be obtained from Bloch states by means of the formulas 1-3 of [Souza2002a] . As you may note there is a freedom of choice in the Bloch orbital’s phase which is reflected in the shape and the spatial extent of the WF. This means that for different phases there will be WFs with different spatial localizations.

This peculiar phenomena arises from the coupling between spin and orbital motions of electrons – spin-orbital coupling (SOC). ear ache tooth pain and headacheWebA Wannier orbital is an atomic orbital, because it is (or at least should be) localized around an atom. Sometimes they are also localized between two atoms, e.g. an sp2 hybrid orbital which as more density between the atoms than on it - but I suggest not to split hairs about that.

This is particularly useful for evaluation of Brillouin-zone integrals on dense grids and searching of Weyl points, and also taking derivatives in the k-space. This approach is similar in spirit to the tight binding approximation, but in contrast allows for an exact description of bands in a certain energy range.
