Hello,

In a BSE calculation, is setting BSENGexx = 0 the same as turning off the exchange part of electron-hole interaction? i.e V=0. Or is it necessary to do something else to do that. Thank you a lot.

Regards,

Dear Bruno,

BSENGexx = 0 eV
will turn off the exchange interaction (ie triplet excitation).

I suggest you use "0 eV" instead of "0 RL", as yambo by default will close shells of Gvectors, it could include the G=0 vector.

Best,

Daniele
