Dear developers,
I have a very simple question to ask: what's in details the difference between the BSE mode = "retarded" vs BSE mode = "resonant" in terms of how the kernel is build up ?
Thank you!

Dear Michele,
the kernel is the same, what is different is how the dielectric function is built.
You can have a look at:
./src/bse/K_diago_compute_epsilon.F
./src/bse/K_output_file.F
Best,
Daniele
