Line Plot from Scientific Research

Real (Re(σ)) and imaginary (Im(σ)) parts of the complex optical conductivity (σ) versus photon energy (ℏω). LDA calculations are shown as yellow lines, and LDA + DMFT calculations as blue lines. Experimental data from reflectometry (Exp. 1) and ellipsometry (Exp. 2) are given by black lines and marked by arrows. LDA + DMFT results show better agreement with experimental data, especially in the visible and UV ranges, for both Re(σ) and Im(σ).
