Dear Yambo devs,

I'm trying to figure out where \epsilon_{GG'}^{-1}(q,\omega) is computed in yambo,

as in equation (6) of the yambo paper.

I think the information in

viewtopic.php?f=10&t=132

is slightly outdated, but so far I see that, for example,

invoking yambo with the -b option to compute the static inverse dielectric matrix results in a call

to X_dielectric matrix in src/pol_function/X_dielectric_matrix.F

I am not sure what happens when the code does

call section(sec_mode,'Static Dielectric Matrix')

though.

Thanks,

Austin Liu
