Calculated diagonal part of the optical conductivity 𝜎 1 𝑥 𝑥 and the optical reflectivity 𝑅 of TmSe treating the 4 𝑓 states as (1) fully localized ( 4 𝑓 in core) (dashed line), (2) itinerant (LSDA) (dotted line), and (3) partly localized (LSDA+ 𝑈 ) (solid line) [384] compared with the experimental data [389] (open squares).
