Is Bethe-Salpeter equation calculations of core excitation spectra embedded in YAMBO code? I mean can we calculate K, L etc. edge absorption spectra of any material using BSE in YAMBO? I am quiet new to this code and your help will be very much appreciable.
with many thanks and best regards Soumyadeep
I am afraid that I am able to comprehend your answer fully. But if you want to compute the EELS, then Yambo surely can do this in various levels of theoretical approximations.
In one week (14 and 15 April 2021) there will be the second part of the virtual YAMBO school and as I see, solving BSE is planned as a hands-on exercise, so maybe you can still join the school and ask this question during the school, see http://www.yambo-code.org/wiki/index.php?title=Tutorials#Modular_overview
Prof. Tatiana Korona thank you very much for the information. Currently core-level spectroscopy can't be calculated in YAMBO code using BSE. Because YAMBO rely on Pseudopotentials, where core electron are not explicitly considered. PAW approach is used to recover all electron wave functions from the corresponding pseudo wave functions, which is still not implemented in YAMBO user versions.
But it can compute valence level excitation spectra using BSE.
