Dear Arash,
Many thanks for Your prompt answer.
By checking the output file of pw2wannier90, I've noticed that the values
of numk and iknum are different in my calculation. By putting the key "nosym
= .true. ," in nscf input file I've fixed it.
Now I have another question. I've used S and P orbitals in the
projections section such as below:
Begin Projections
Si19:s;px;py;pz
Si20:s;px;py;pz
End Projections
As is clear, I've put 4 orbital (s,px,py,pz) in each silicon atom for
calculation of 8 Wannier function. The calculation finished perfectly and
the Interpolated bands was satisfying.
Now I want to use hr_plot data to calculate the On-site and hopping terms.
So I want to know the order of H_{mn} stored in hr_plot.dat.
According to my input file, I guess that order of orbitals is as follow:
1-s, 2-px,3-py,4-pz,5-s,6-px,7-py,8pz
Now my question is this: Am I right about the correct order of orbitals? If
it's not true what is the correct order of orbitals?
Would You do a favor by providing me with a detailed answer about it if
it's possible? It would be a great help and I'll appreciate it.
Sincerely Yours
Riemann
