Dear Developers,
I did some calculations with yambo -o c -k hartree
and I have output files for q1, q2, ...
would you please tell me what is the meaning of these
Qs?
and which of these files is important to plot(e.g. for epsilon)?
I saw in the tutorial that plot the spectrum just for the q1!!
All the best

Dear S. Atei,
The q's are the transferred momenta, which are important if you are interested to electron energy loss spectra. If you need the optical sepectrum only you are interested to q1, which is the limit q->0 and you can avoid to calculate the other q just setting:

Code: Select all

%QpntsRXd				
1|1|		#	(Xd)	Transferred momenta
%

in the input file.
