We used a 6x6x6 mesh of q points for the determination of Re Σ because the integral over E′ makes the calculation very computationally intensive. An 8x8x8 mesh was used for Im Σ.

It has been demonstrated that in order to obtain good agreement between theory and experiment for the bandwidth of simple metals at T = 0 using an LDA + GW approach, it is necessary to go beyond the random-phase approximation when determining the screened interaction. A Hubbard-type dielectric function based on LDA was used to calculate renormalized bandwidths in J.E. Northrop, M.S. Hybertsen, and S.G. Louie, Phys. Rev. B 59, 819 (1987). We are mainly concerned with the general behavior of the bandwidth when the electron temperature is raised, so we use RPA in this work and leave a more accurate determination for later study.

xc(r) is a constant, so we chose not to add it to Re Σ. The addition of a constant to Re Σ does not change the relative quasiparticle energies (i.e., the bandwidth).
