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!

tnons parameter in RF calculation (Optic)
Dear Abinit users, Looking through Optic tutorial, in the input file toptic_1.in I found the variable tnons = 72*0. I was trying to figure out the physical meaning of this parameter but still I'm a bit confused. So, could anyone explain the meaning of it in a simplified manner? Should it always be 7...
