BSE absorption spectrum at finite k

Hello,
I am interested in obtaining the BSE absorption spectrum at finite k values. I have obtained them for the usual k=0 and I would like to compare them with our TDDFT results at finite k. Are there any tricks or suggestions?
Thanks

Dear Kushal,
there is an experimental version of yambo for BSE calculation at finite q (transferred momentu k-k'), but it is still under testing and not in the GPL release. It will be released under GPL, but I cannot say you at this moment when it will happen.
Best,
Daniele

Dear Daniele,
I am also interested in the finite q calculation. Will this code be available in GPL soon? Thanks.
Best,
Feng

Dear Feng,
The finite-q Bethe Salpeter is in the list of the new features of the next release.
Unfortunately, there is not yet a release date, hopefully in the next spring.
Best,
Daniele
