Bogoliubov self-consistent and second-order Green's function methods for attractive fermionic interactions
Mauricio Rodr{í}guez-Mayorga, Johannes Tölle, Pierre-François Loos
Describing fermionic systems with attractive interactions, such as superconductors and atomic nuclei, beyond the mean-field level remains a central challenge. In this work, we inve…
An Algebraic-Diagrammatic Construction for Vertex Corrections to the Self-Energy
Antoine Marie, Johannes Tölle, Pierre-François Loos
The approximation -- the second-order self-energy beyond -- is known to violate some fundamental analytic properties of the self-energy. In particular, its lack of posi…
From Full Dynamic to Pure Static: A Family of -Based Approximations
Pierre-François Loos, Johannes Tölle
We introduce a systematic hierarchy of one-body Green's function methods derived from the approximation, constructed by progressively reducing the dynamical content of the sel…
Reference Energies for Non-Relativistic Core Ionization Potentials
Antoine Marie, Loris Burth, Pierre-François Loos
Deep-lying core electrons carry highly localized, site-specific information that forms the basis of X-ray photoelectron spectroscopy. Accurately predicting their associated core io…
Equation Generator for Equation-of-Motion Coupled Cluster Assisted by Computer Algebra System
Raúl Quintero-Monsebaiz, Pierre-François Loos
We present an equation generator algorithm that utilizes second-quantized operators in normal order with respect to a correlated or non-correlated reference and the corresponding W…
