Comments on All-electron self-consistent GW in the Matsubara-time domain: Implementation and benchmarks of semiconductors and insulators

Chu et al. recently reported extensive results of local density approximation (LDA) and of four (4) different Green function and dressed Coulomb (GW) approximation calculations of electronic properties of several semiconductors and insulators [Phys. Rev. B 93, 125210 (2016)].
