Dear Mr. Nishihara
I want to calculate spin-orbit effects on the bandstructures of GaN.
But Here is this :
I have used US pseudopotentials:
1.Ga.rel-pbe-dn-rrkjus_psl.0.2.UPF
2.In.rel-pbe-dn-rrkjus_psl.0.2.2.UPF
And Spin-orbit settings in BURAI is as below:

And the band-structure I got is as below :
I have tried to understand for hours what happened here. Could you please take a look here?
For spin-orbit coupling I have Followed the example07 of Pw package of quantum espresso

Moin! In Dresden habe ich über Freunde von Plinko erfahren und wollte es einfach mal ausprobieren. Ich war anfangs eher skeptisch, weil es so simpel aussieht. Aber als ich ein paar Kugeln laufen ließ, war ich direkt dabei – jedes Mal diese Spannung, wohin sie fällt. Ich hatte sogar einen Abend, an dem ich Verluste ausgleichen und am Ende noch Gewinn machen konnte. Besonders bei plinko deutschland habe ich gemerkt, dass genau solche Überraschungen den Reiz ausmachen.
Thank you , Mr. Nishihara
It may be a bug.
It seems number of bands is too small for non-colinear spin.
I will fix it in the future.
For the present, please set #band to be twice.
In the DOS calculation following error ocurred :
Error in nscf calculation was: ethr = 2.78E-09, avg # of iterations = 22.3 Message from routine efermit: internal error, cannot bracket Ef
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Error in routine tetra_weights (1): bad Fermi energy %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
stopping ... -------------------------------------------------------------------------- MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode 1.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes. You may or may not see output from other processes, depending on exactly when Open MPI kills them.
And to add when i wanted to calculate DOS error message was " internal error : can't bracket Ef"
certainly it's a Fermi level error. I had used degauss .01 and 10 10 10 k-point in DOS calculation.
