Dear Wien2k users ;
I extracted the A,B,C coefficients for 2 following klist : (with TEMP switch in case.in2)
klist1:
1 0 0 0 8 1.0 -7.0 1.5 8 k, div: ( 2 2 2)
2 0 0 4 8 1.0
3 0 4 0 8 1.0
4 0 4 4 8 1.0
5 4 0 0 8 1.0
6 4 0 4 8 1.0
7 4 4 0 8 1.0
8 4 4 4 8 1.0
END
-------------------------------------------------------
klist2:
1 0 0 0 2 1.0 -7.0 1.5 8 k, div: ( 2 2 2)
2 1 1 -1 2 1.0
3 1 -1 1 2 1.0
4 2 0 0 2 1.0
5 -1 1 1 2 1.0
6 0 2 0 2 1.0
7 0 0 2 2 1.0
8 1 1 1 2 1.0
END
-------------------------------------------------------
the points in klist1:
0.00000 0.00000 0.00000
0.00000 0.00000 0.50000
0.00000 0.50000 0.00000
0.00000 0.50000 0.50000
0.50000 0.00000 0.00000
0.50000 0.00000 0.50000
0.50000 0.50000 0.00000
0.50000 0.50000 0.50000
-----------------------------------------------------
and I think klist2 is equivalent to klist1. Cause for example for the 2nd kpoint in klist2 we have (0.5,0.5,-0.5) and if I add this point with (0,0,1) I will have (0.5,0.5,0.5) so the 2nd point in klist 2 is equivalent to the 8th point in klist1.
Bu I don't understand why the result of A,B,C is different for these klists?
A,B for klist1(8th kpoint):(0.516961906266977,1.032507548898117E-002) (-0.360728898786504,-7.136271919102941E-003)
corresponding A,B for klist2(2nd kpoint):(0.490077747938069,-0.202996849814049) (-0.282368518420407,0.116960869917412)
and this point is very important for me. because I calculate Wannier functions with my interface code and Wannier Functions need a klist such as the mentioned klists (non-reduced) and Although the algorithm of my code works correctly,because of changing A,B,C my result is not correct.
I would appreciate your help if you can guide me.
Best Regards,
Fatemeh
