optical absorption plot

Deals with issues related to computation of optical spectra, in RPA (-o c) or by solving the Bethe-Salpeter equation (-o b). Includes local field effects, excitons, etc.

optical absorption plot

Post by niloufar » Wed Nov 11, 2020 6:46 pm

Hello dear developers,

I just started to run yambo code and as a first step I got the optical absorption of Cs2PbBr3 with ( yambo -F yambo.in_IP -o c ) But when I plot the .eps files, I got the same numbers in all axises (x,y,z). I mean, when you plot them together, you can't see any differences. Is there a problem? How can I fix that?

Thank you in advance

Dear Niloufar,

can you attach your input and output files (attachments bottom bellow)?
when uploading file you need to rename it with a supported format e.g. (.zip or .txt)

Many thanks,
Daniele

Hi Daniele,
Thanks a lot for helping. I attached the input file and the outputs.

sincerely,
Niloufar

Dear Niloufar,
the spectra are very similar, but not identical.
It seems your system is homogeneous along that direction.
You can check the symmetries in your report or qe output, if they are recognised.

Best,
Daniele
