COHSEX for Yambo 5.2.3

Concerns issues with computing quasiparticle corrections to the DFT eigenvalues - i.e., the self-energy within the GW approximation (-g n), or considering the Hartree-Fock exchange only (-x)

COHSEX for Yambo 5.2.3

Post by sdwang » Fri Sep 13, 2024 3:46 am

Dear all,
I am a new user and trying to do a cohsex calculation with yambo 5.2.3, and should I use the yambo or yambo_sc executable?
My option for cohsex is >yambo -r -x -d -k hartree -g n -p c, and is it OK?

Thanks!

Dear Shudong,

it depends if you want to do a self-consistent calculation or just a one shot calculation.
Please note, the self-consistent calculation should work, but it is still experimental.

Best,
Daniele
