+2SOSEX self-energy made positive semi-definite
Fabien Bruneval, Arno Förster, Yaroslav Pavlyukh
The formulation of vertex corrections beyond the approximation within the framework of perturbation theory is a subtle and challenging task, which accounts for the wide variet…
Periodic implementation of the random phase approximation with numerical atomic orbitals and dual reciprocal space grids
Edoardo Spadetto, Pier Herman Theodoor Philipsen, Arno Förster +1
The random phase approximation (RPA) has emerged as a prominent first-principles method in material science, particularly to study the adsorption and chemisorption of small molecul…
Beyond quasi-particle self-consistent for molecules with vertex corrections
Arno Förster
We introduce the self-energy in the quasi-particle self-consistent (qs) framework (qs). Here, is the two…
Why does the approximation give accurate quasiparticle energies? The cancellation of vertex corrections quantified
Arno Förster, Fabien Bruneval
Hedin's approximation to the electronic self-energy has been impressively successful to calculate quasiparticle energies, such as ionization potentials, electron affinities, o…
