Second order non-linear optical response using GW or BSE
Posted: Tue Nov 12, 2019 9:13 am
Dear Abinit users,
Is there any way to calculate frequency-dependent non-linear optical response beyond RPA in ABINIT? The Optic tutorial doesn't describe how to include excitonic effects in this kind of calculations. Is there any way to include GW and BSE approach? I badly need it.
Thank you!
