Symmetry-adapted Wannier functions (SAWFs)
Dear VASP team,
I am asking whether VASP can do "Symmetry-adapted Wannier functions (SAWFs)". If so, which version of VASP can do this?
Symmetry-adapted Wannier functions (SAWFs) are Wannier functions that are constructed so that they transform according to the symmetry operations of the crystal. They are extremely useful when building tight-binding models, analyzing chemical bonding, studying topological materials, and preserving crystal symmetries in Wannier90 calculations.
It seems to me that this is done in the Wannier90 code. However, in order to do it, it needs the VASP code to generate the so-called "wannier90.dmn" file, (it seems Quantum ESPRESSO code can do this via its interface code "pw2wannier90.x"). Then the wannier90.x will use it to do the SAWFs.
Please let me know how to do this in VASP.
Thank you very much!
Best,
Hong
