[QE-users] 回复: Plasmons

[Oleksandr Motornyi]

I would start with turbo_eels.x code of TDDFT module that is distributed 
with QE. Of course you have to cautious while dealing with a 2D system 
(i.e. check convergence w.r.t to vacuum and etc) but in principle you 
can obtain momentum-dependent dielectric function.

Best regards
