ABINIT Discussion Forums

Hi dear users.
Is it possible to calculate other optical constants, such as refractive
index n(ω), absorption coefficient α(ω), reflectivity
R(ω) and electron energy-loss spectrum L(ω) by abinit?
I find calculation of ε1(ω) and ε2(ω) in lesson_optic but no information about other constants.
Thankful.

Dielectric function contains all the necessary information. Check some textbook to find out their relationships with others.
