    • G = 411 for silicon and argon, respectively. On the contrary, the long-range model in TDDFT turned out to require only 59 G vectors, as an RPA calculation. The self-energy shift for silicon (GW-RPA calculation) has been obtained using the GW corrections, calculated in the plasmon pole model approximation (see Ref. 29); whereas for solid argon, a “scissor operator” (of 6.0 eV) has been applied to simulate the GW corrections, and hence to reproduce the experimental quasiparticle gap. The broadening used for silicon in Figs. 11 and 33 was 0.05 eV (absolute Lorentzian broadening). In addition a relative broadening (Gaussian + Lorentzian) of 2% has been applied. The broadening used for argon in Figs. 22 and 44 was 0.05 eV (absolute Lorentzian broadening)
