Re: paw+gw with spin-orbit [SOLVED]

raul,
how would you add the soc effect to the gw calculations?
And the way, does the new version of abinit supports GW+SOC?

Re: BSE code does not support metals?

Thank you gmatteo for your reply. As I mentioned the system I working on are insulators with large gap. I'm using the default value of occupy, see the input files.

BSE code does not support metals?

Hello all,
I have problem running BSE, I have an interface between two insulators SrTiO3 and LaAlO3. but I got an error saying:
BSE code does not support metals
I do not know why it assumed metal and it is an insulator?

converging nband?

Hi all, I need to calculate the optical absorption of SrTiO3. I found when I use "bs_loband=1" and "nband=20", the results looks good compared with experiment. But when I increase # of band (e.g. nband=30)which the curve should get converge I noticed results go bad compared with ...

so I just noticed something;
in the second run of the input file of tbs_2.in, it is mention this:
irdscr 1 # Read the SCR file produced in tbse_1
so do I need to make it

hello there,
from the tutorial of BSE:
nband2 105 # bands treated in the CG algorithm
nbandkss2 100 # bands written in the KSS file.
but they did not mention why they chose these numbers! this tutorial should be re-written!!
