Our results indicate a charge-transfer mediated mechanism ... WebHere are four criterions of high-quality WFs. 1. Perfect fitting to the DFT bands in the energy range you are interested in. 2. Keep the atomic orbital symmetry. 3. Well localized. 4. As small number of WFs as possible. There are three important steps to reach four criterions. 1. Choose projectors. 2. Choose disentanglement energy window. 3.

http://www.wannier.org/wp-content/uploads/2024/03/tutorial_cecam.pdf WebA 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. A great program to obtain Wannier orbitals is wannier90.

Wannier functions are often used to interpolate bandstructures calculated ab initio on a coarse grid of k-points to any arbitrary k-point. 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.
