Dear all, I am interested in calculating the static bare susceptibility \chi(q) = 2/N_k \sum_{knm} \frac{f_{k+qn}-f_{km}}{\epsilon_{k+qn}-\epsilon_{km}} If I understand correctly, the \chi(q) is electron-phonon contribution to the static phonon self-energy assuming constant matrix element. Does EPW ...

The system administration seems not really happy when I use outdir ='./' since it will affect other works. I ran on only 1 node with 24cores and outdir='/tmp/', afte...
