Quasiparticle self-consistent $GW$ method; a basis for the independent-particle approximation

Takao Kotani, Mark van Schilfgaarde, Sergey V. Faleev

We have developed a new type of self-consistent scheme within the $GW$ approximation, which we call quasiparticle self-consistent $GW$ (QS$GW$). We have shown that QS$GW$ rather we…
