Dear all,
what is the exact form of the Drude contribution associated with the complex variable DrudeWBS?
Thanks,
Alejandro.

Dear Alejandro,
I never used it, anyway looking into the code, this variable it is meant to add the Drude contribution (metallic systems), in the BS calculation. In inout you give real and imaginary (damping) part of the Drude plasmon, and it is used to build up the Drude propagator:
The expression is coded in:
/src/pol_function/X_drude.F
and you can have a look to:
R.D. Mattuck "A guide to Feynmann diagrams in the Many-Body problem", pag. 197.
or Fetter Walecka "Quantum Theory of Many-Particle systems" chap 5.
Hope it helps,
Daniele
