Lindhard response function X(q),

Dear all,
I am new user to EPW code. I wanted to ask if I can calculate and plot the Lindhard response function X(q) as done in the reference (https://iopscience.iop.org/article/10.1 ... 48X/ab8522) using the EPW code.

I would be very grateful for your help.

Regards

What are the underlying factors that contribute to certain superconductors exhibiting a high electron-phonon coupling constant (λ) while having a comparatively low critical temperature (Tc), and is this disparity primarily attributed to mass renormalization effects dominating in these specific systems?

Why some superconductors have a large λ but a low Tc? Is it because mass renormalization dominates in these systems?
