Hi Animesh,

The unit of phonon frequency used in the freq file in Ry. But while reading_ephmat we convert freq to eV unit.

Hi Zhao, It looks like the error message indicates a memory issue. I have a few suggestions that might help. First, the Wannierization seems problematic. As shown in your output file, the spread of some Wannier centers is unusually large, around 17-20 Ang, which is quite unexpected. I suggest adjust...

Hi Bhawna,

When you specify ldisp = .true., you need to specify k-grid not a k-path.
If you want to read the "L" point coordinates, you can set ldisp = .false. and trans = .false.

Dear Fumihiro, To draw "guided lines to the eyes" over an anisotropic superconducting gap as shown in Figure 4, we take an average over the minimum and maximum gap distributions in the lower and upper gap regions at each temperature. Then join the points. There is also another way to fit the anisotr...

Hi Elijah, The PDWF works only for entangled bands, while MRWF is only used for isolated bands. The error message while running “wannier90.x -pp graphene” is because the PDWF technique is not implemented in the release W90 version. That's why you get unrecognized keywords. However, the "atom_proj" i...
