Dear all,
I want to calculate wave function overlaps in order to extract some parameters for a collaborator. Since I want the overlap in a heterostructure of 2 monolayers for the wave functions of the single layers (i.e., I need 3 calculations), the easiest solution would be to look at the changes in the projection on the atomic states using projwfc. Yet, this local basis is not complete and I would like to know how "much" is missing. I found the wfck2r.f90 code. Yet, I think there are several problems with using this and maybe someone can comment. I think I once read that one cannot easily compare the wave functions between different calculation because of an arbitrary phase shift. Is this correct? Because if I can't do this, then I don't even need to consider using the code. If I can do it, then am I right, that the wfck2r code does not include the SOC case for output in octave format? Because in line 248, only pol=1 is used... Another problem I noticed is a huge difference in sizes of the octave output and the binary output. The octave output was in my test case about 68 MB while the binary file was 6 GB. Kind regards Thomas -- Dr. rer. nat.
