 Hi, 

    Maybe I have not illustrate problem clearly.
I want to perform EPC calculation on a supercell.
 Take NaCl as a example,


The example looks meaningless, NaCl is an insulator. 







don't phonons interact with electrons in insulators?

Hi Stefano, 

Of course,  they do, but  it seemed to me that there was an intention to calculate \lambda. 
It might be that I missed something but I never hurd that NaCl is a superconductor .  Just in this context I suggested that it is "meaningless".

Bests,
Eyvaz.
