Electronic contributions to the excited state XUV absorption. (a) The theoretically predicted state-filling of holes (light blue) and electrons (light pink), broadening (grey), and renormalization (light orange) contributions for a 1.5 × 10²⁰/cm³ photoexcited carrier density. The theoretical predictions are compared to the experimental 100 fs differential absorption (black solid line). The dashed lines indicate the 95% confidence intervals of the measurement. (b) The orange shaded area indicates the sum of the electronic contributions predicted in panel (a). The broadening, renormalization, and state-filling combine to accurately predict the increased absorption at energies below the Δ₁ point. The decreased absorption at the L₁ point is predicted at the correct energy, but the amplitude of the L₁ and the L₃ features are underestimated when only the electronic contributions are considered.
