In this perspective, the various measures of electron correlation used in wave function
theory, density functional theory and quantum information theory are briefly reviewed. We …

We present algorithmic and implementation details for the fully self-consistent finite-
temperature GW method in Gaussian Bloch orbitals for solids. Our implementation is based …

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 …

Due to the infinite summation of bubble diagrams, the GW approximation of Green's function
perturbation theory has proven particularly effective in the weak correlation regime, where …

The fully self-consistent GW (sc GW) method with an iterative solution of the Dyson equation
provides a consistent approach for describing the ground and excited states without any …

One-particle Green's functions obtained from the self-consistent solution of the Dyson
equation can be employed in the evaluation of spectroscopic and thermodynamic properties …

The accurate ab-initio simulation of molecules and periodic solids with diagrammatic
perturbation theory is an important task in quantum chemistry, condensed matter physics …

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) …

By recasting the non-linear frequency-dependent GW quasiparticle equation into a linear
eigenvalue problem, we explain the appearance of multiple solutions and unphysical …

One-particle Green's function methods can model molecular and solid spectra at zero or non-
zero temperatures. One-particle Green's functions directly provide electronic energies and …
