Dielectric constant is unreasonably different w/ and w/o spin-orbit
Posted: Thu Aug 21, 2014 6:55 pm
Hi,
I'm using vasp.5.3.5 and having problem when calculating dielectric constant with spin-orbit coupling. While the band structure w/ spin-orbit is almost identical to that w/o spin-orbit. The dielectrics are completely different.
Any explanation for the difference?
Thanks
To calculate epsilon I use:
LOPTICS = T
LRPA = T
for spin-orbit calculation I add:
LSORBIT = T
The link below is the imaginary part of epsilon.
