موضوع: cosidering nonlocal effect in dielectric response

Hi,

I'm trying to study plasmonics in the semi metallic graphene nanoribbons considering nonlocal effect. I'm trying to calculate dielectric response (cosidering nonlocal effect) using yambo. I would really appreciate it, if anyone would answer below questions.
1- Is the gw+bse a good strategy for this goal? or should I use rpa or some thing else?
2- how can I include nonlocal effect in my calculation? I found some parameters like BSEQptR and QpntsR. Are they the parameters I should consider? if yes, which one and how?

Please help.

I didn't find the right solution from the Internet.
