Lindhard response function

[oleg_feia]

Hello,

I want to calculate Lindhard susceptibility X(q,w=0). I tried to use this manual https://www.vasp.at/wiki/index.php/Diel ... ies_of_SiC ,
but looks like it is possible to get X(0,w) from there.
Can somebody, please, provide me step by step manual to solve this problem?

Unfortunately at the moment there is no output option for the dielectric function at zero frequency and non-zero q point.
But there are routines which calculate these quantities.

We will put the output of these quantities on our to do list.

Thanks for the answer!

Can you, please, give me links on these routines? I tried to google them, but failed.

Do you mean you want to know where in the code these functions are calculated, so that you can manually modify the code to print them out?
