Hi, Well, basically all you need is already available and your task is just to adopt the different pieces and assemble it together. Of course you are right, w2w calculates the required matrix elements. Unfortunately, I've never looked into the code myself, so cannot guide you specifically.

[Wien] Computing matrix elements using cell-periodic Bloch functions

2021-06-23 Thread Andrew Parks
Hello Wien2k Community, I am seeking advice on the best approach for extracting/using information about the eigenvectors that is not available within the current Wien2k code (as far as I know). For a custom k-point mesh (e.g. a 2D grid), I want to calculate the band-diagonal overlaps of the
