Yambo Community Forum

Hi,

Yambo does not reproduce correct DFT+SOC energies from QE when running HF.

For the perovskite with SOC (50 occupied bands) the QE DFT band energies for chosen k-point
for states 49-52 are:
2.2851 2.2851 3.7406 3.7406

Yambo writes

# Hartree-Fock Components and Corrections
#
# K-point Band Eo Ehf DFT HF
#
10.00000 50.00000 5.77299 10.31570 -8.14541 -3.60270
10.00000 51.00000 5.89579 10.50171 -8.32835 -3.72243

The same excercise with DFT without SOC is OK (gap between 25 and 26).

Dear Malgorzata,
thanks for reporting on yambo.

From these few informations it is hard to understand what is happening.

I guess this is the output of "yambo -x"
Could you please attach the pwcf output together with the yambo report and output files ?

Best,
D.

Thank you Davide,

One more stupid question: how to make attachements in forum?
(I do not see where to click)

Malgorzata

When you hit "post a reply" there should appear an "upload attachments" section, just below the "submit" button.

Best,
D.

I attached a moment ago and I even do see my answer, not saying about files....
I do again.

Seems it doesn't work too.
I try again, because I do not see the attachement to my post
when go out from submission.

No way, I go to upload attachement, browse, add file and comment
and after add file the system is back to draft and no attachement is seen.
Then I try again to upload and the story from the begin without memory
of previous attachement...

Maybe because of tar? or files are too big?
I try simple scf.in to check

For scf.in there was error "the extension is not allowed"
I check yambo o.hf file - and this is also not allowed.

Dear Malwi,

Please pay attention to the allowed file suffix. If you rename your file as .txt, or you upload a .tar.gz it should work.
Next, you can finn your signature with your affiliation so you do not need to add it manually at each post.

Best,

Hi all

This is the file that Gosia cannot upload. I hope it works for me...

Thank you Juanjo and Daniele.

Dear all,
I had a quick look to the files.

In the pwscf output I see In the yambo report which is consistent with the shift done by yambo and reported as the Fermi level:
Fermi Level [ev]: 1.605075

Same in the yambo output Please pay attention: The pwscf energies you reported in the previous post are for states from 40 to 43 !

Best,
D.
