First question:
I'd expect that a spin-polarized Au calculation converges to a zero
moment solution, which should be identical to the non-spinpolarized one.
Do the spin-polarized+so and non-spinpolarized+so calculations give the
same DOS ??
Did you allow for symmetry break in the
OK...except the finite SH harmonic expansion suffers from aliasing, so
(0,0) changes. I did a quick check and the default (14) is about 1E-6
off whereas going up to 31 was about converged to about 1E-7.

Dear colleagues
With reference to my earlier post, which was concerned with the optical
properties of gold with spin-orbit coupling, I have a query that I hope to find
an answer for it.
To calculate the dielectric properties of Gold (Au) I used spin polarized
calculation and everything went
Remember, in output0grr we calculate just the average of grad rho / rho
For this average inside the sphere, only the lm=0 term is essential,
non-spherical terms of the fit of grad rho/rho do not enter.

Hi Fatima,
Trying different numbers of points around H means that you will be
changing the delta_K you take to fit the parabola.
Besides this, you must also try a band structure with more K_points. Fix
the delta_K and see how the effective mass changes with the number of
points inside the
Thank you very much Luis for suggestion.
I got the point just correct me. I enlarged the band structure near VBM and
I see here I have a sharp parabola like shape

Hi Fatima,
The effective mass approximation works near the band extrema (maxima and
minima). You have to choose some points around them and fit the parabola.
Try different number of points (distances from the maximum or minimum) and
check the consistency of the calculated effective mass.
Dear Wien2k Users,
>From the band structure attached in below link I can calculate the electron
effective mass using parabola fitting but I do not know how to calculate
the hole effective mass as the shape of the VBM is not parabolic.
I wonder if someone from the mailing list could help me.
