Beyond quasi-particle self-consistent $G W$ for molecules with vertex corrections

Arno Förster

We introduce the $Σ^{BSE} @ L^{BSE}$ self-energy in the quasi-particle self-consistent $G W$ (qs $G W$ ) framework (qs $Σ^{BSE} @ L^{BSE}$ ). Here, $L$ is the two…

Why does the $G W$ approximation give accurate quasiparticle energies? The cancellation of vertex corrections quantified

Arno Förster, Fabien Bruneval

Hedin's $G W$ approximation to the electronic self-energy has been impressively successful to calculate quasiparticle energies, such as ionization potentials, electron affinities, o…

Fully dynamic G3W2 self-energy for finite systems: Formulas and benchmark

Fabien Bruneval, Arno Förster

Over the years, Hedin's $G W$ self-energy has been proven to be a rather accurate and simple approximation to evaluate electronic quasiparticle energies in solids and in molecules.…
