Plasmon dispersion using yambo

[sitangshu]

Hi folks,

I am trying to understand surface plasmons in metals. Is there a way to get plasmon dispersion using yambo?

Dear Sitangshu,

you can calculate EELS spectrum either at RPA level or BSE level, see e.g. https://pubs.acs.org/doi/abs/10.1021/ac ... tt.3c03863
When dealing with metals, you need to pay attention to intraband transitions, we are currently working on an accelerated method to include them, but it is still under testing phase. In the meanwhile, please have a look at this paper to take them into account reasonably:

Best,

Daniele
