The GW approximation in electronic structure theory has become a widespread tool for
predicting electronic excitations in chemical compounds and materials. In the realm of …

The Bethe–Salpeter equation (BSE) formalism is steadily asserting itself as a new efficient
and accurate tool in the ensemble of computational methods available to chemists in order …

Accurate computational predictions of band gaps are of practical importance to the modeling
and development of semiconductor technologies, such as (opto) electronic devices and …

We review state-of-the-art electronic structure methods based both on wave function theory
(WFT) and density functional theory (DFT). Strengths and limitations of both the wave …

Upon ionization of an atom or a molecule, another electron (or more) can be simultaneously
excited. These concurrently generated states are called “satellites”(or shakeup transitions) …

We describe our efforts of the past few years to create a large set of more than 500 highly
accurate vertical excitation energies of various natures (π→ π*, n→ π*, double excitation …

The GW approximation has recently gained increasing attention as a viable method for the
computation of deep core-level binding energies as measured by X-ray photoelectron …

We test the performance of self-consistent GW and several representative implementations
of vertex-corrected G 0 W 0 (G 0 W 0Γ). These approaches are tested on benchmark data …

We use the GW100 benchmark set to systematically judge the quality of several perturbation
theories against high-level quantum chemistry methods. First of all, we revisit the reference …

In recent years, Green's function methods have garnered considerable interest due to their
ability to target both charged and neutral excitations. Among them, the well-established GW …
