Dear all,
I was wondering if there is a way in YPP to interpolate not only the band structure but also the "spectral function" (-1/pi Im(G)) (or any part of the Green's function obtained from yambo -g g -d -k hartree) along high symmetry lines and not on the regular grid?
I saw a lifetime plot in the LiF example but I don't think it was mentioned if this was made with ypp or with an external script!
Thanks in advance for your help!

Dear Chris,
electron lifetime is calculated by yambo: yambo -l option.
It is calculated as described in section 4.2 of the yambo paper:
https://iopscience.iop.org/article/10.1 ... 48X/ab15d0
It is calculated for the k point grid contained in your grid. Unfortunately, there is no interpolation method in ypp for lifetimes so you need to have the k point of interest in your grid.
Best,
Daniele
