G=0 term in BSE kernel

[ramiroflores]

Hello,

When momentum cancels, the G=0 term in the electron-hole exchange integral is eliminated for BSE calculations. However, this terminology is important for studying vertical and horizontal separation. I'm wondering if it's possible to add the term G=0?

Dear ramiroflores ,

please add your name and affiliation in your posts. This is a rule of the forum. You can do once for all by filling the signature in your user profile.

You can include the G=0 term in the exchange by setting:

Code: Select all

Lkind="full" 

in the BSE input file.

Best,
