From Full Dynamic to Pure Static: A Family of $GW$-Based Approximations

Johannes T\"olle, Pierre-Fran\c{c}ois Loos

A hierarchy of GW approximations shows that reducing dynamical content in the self-energy yields reliable quasiparticle energies from simpler static schemes.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Consistently derived partially static schemes can yield reliable quasiparticle energies while significantly simplifying the underlying eigenvalue problem; the novel static Hermitian self-energy produces results remarkably close to those of qsGW.

C2weakest assumption

That the specific downfolding and progressive removal of dynamical content preserve the essential physics of the original GW self-energy across the molecular test set without introducing uncontrolled errors.

C3one line summary

A new family of GW-based methods is obtained by progressively staticizing the self-energy, with partially static members delivering reliable molecular ionization energies at reduced cost and a novel static Hermitian self-energy matching qsGW results.
