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 …

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 …

Abstract yambo is an open source project aimed at studying excited state properties of
condensed matter systems from first principles using many-body methods. As input, yambo …

With the aim of completing our previous efforts devoted to local and Rydberg transitions in
organic compounds, we provide a series of highly accurate vertical transition energies for …

Methods able to simultaneously account for both static and dynamic electron correlations
have often been employed, not only to model photochemical events but also to provide …

The performance of different GW methods is assessed for a set of 24 organic acceptors.
Errors are evaluated with respect to coupled cluster singles, doubles, and perturbative …

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 …

The GW-Bethe–Salpeter equation (BSE) method is promising for calculating the low-lying
excitonic states of molecular systems. However, so far it has only been applied to rather …

We present the formalism and implementation of quasi-particle self-consistent GW (qs GW)
and eigenvalue only quasi-particle self-consistent GW (ev GW) adapted to standard …

The predictive power of the ab initio Bethe-Salpeter equation (BSE) approach, rigorously
based on many-body Green's function theory but incorporating information from density …
