electron-electron scattering rate

Dear users,

I want to calculate electron-electron scattering rates in metal based on GW approximation and RPA as shown in this paper (http://journals.aps.org/prl/abstract/10 ... 102.076803) . Is it included in the EPW ? Please let me know.

Thanks
Ajit

Dear Ajit,

Within EPW you can only calculate the electron-phonon scattering rate; the electron-electron one needs to be computed using a GW code.

Dear Carla,

Thanks for your reply. Is there a GW code within Quantum espresso ? If not, can you please direct me to any available codes?

Thanks
Ajit

Dear ajitkv,

You can use the Yambo code: http://www.yambo-code.org/

Dear Samuel,

Thank you for your response. I will look into it.

Dear Samuel,

Does the yambo code also calculates electron scattering rates due to phonon scattering like EPW? I read some discussion on the yambo website, but it was not explicitly specified. So, i am curious. Please let me know

Thanks

Dear Ajit,

To my knowledge, it does not.
