[Pw_forum] epsilon.x

[Mansoureh Pashangpour]

Dear all,
I would like ask 3 questions about epsilon.x run.
 1. How can I find Im part of epsilon after offdigonal calculation of
epsilon (I can obtain dielectric function tensor but how can I compaire the
results with experimental results)?
1.How can I have spin-orbit interaction in epsilon calculation?
3. How can I have GW aproximation in a epsilon calculation?
I look forward to hearing form you,
Regards,
