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 …

We review the many-body Green's function Bethe–Salpeter equation (BSE) formalism that is
rapidly gaining importance for the study of the optical properties of molecular organic …

The 0–0 energies of 80 medium and large molecules have been computed with a large
panel of theoretical formalisms. We have used an approach computationally tractable for …

We perform benchmark calculations of the Bethe–Salpeter vertical excitation energies for
the set of 28 molecules constituting the well-known Thiel's set, complemented by a series of …

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 …

Quantum chemical calculations are important for elucidating light-capturing mechanisms in
photobiological systems. The time-dependent density functional theory (TDDFT) has …

In commonly studied GFP chromophore analogues such as 4-(4-hydroxybenzylidene)-1, 2-
dimethyl-1H-imidazol-5 (4H)-one (PHBDI), the dominant photoinduced processes are cis …

The introduction of GW approximation to the electron's self‐energy by Hedin in the 1960s,
