Dear Prof. Blaha Thank you for your answer. yes you are right it happens for spin-polarized systems. But I cann't understand what is the problem. There are 6 valence bands in ZrTe2 with and without SO splitting is appear in the A point. but for ZrTeSe I see different situation, without SO 6 valence bands and with SO 12 valence bands. I think something is wrong.
Thank you for your attention Best Regards ________________________________ From: Peter Blaha <pbl...@theochem.tuwien.ac.at> To: A Mailing list for WIEN2k users <wien at zeus.theochem.tuwien.ac.at> Sent: Sat, April 23, 2011 7:31:44 AM Subject: Re: [Wien] mbj potential in the case without inversion symmetry I guess the UG says, that this restriction applies ONLY for spin-polarized systems !!!
