Abinit 2025: New Capabilities for the Predictive Modeling of Solids and Nanomaterials
Matthieu J. Verstraete, Joao Abreu, Guillaume E. Allemand +71
Abinit is a widely used scientific software package implementing density functional theory and many related functionalities for excited states and response properties. This paper p…
Capturing electronic correlations in electron-phonon interactions in molecular systems with the GW approximation
Antonios M. Alvertis, David B. Williams-Young, Fabien Bruneval +1
Electron-phonon interactions are of great importance to a variety of physical phenomena, and their accurate description is an important goal for first-principles calculations. Isol…
Direct comparison of many-body methods for realistic electronic Hamiltonians
Kiel T. Williams, Yuan Yao, Jia Li +22
A large collaboration carefully benchmarks 20 first principles many-body electronic structure methods on a test set of 7 transition metal atoms, and their ions and monoxides. Good…
Reproducibility in Calculations for Solids
Tonatiuh Rangel, Mauro Del Ben, Daniele Varsano +13
Ab initio many-body perturbation theory within the approximation is a Green's function formalism widely used in the calculation of quasiparticle excitation energies of solids.…
Effects of quantum confinement on excited state properties of SrTiO from ab initio many-body perturbation theory
Sebastian E. Reyes-Lillo, Tonatiuh Rangel, Fabien Bruneval +1
The Ruddlesden-Popper (RP) homologous series SrTiO provides a useful template for the study and control of the effects of dimensionality and quantum confinem…
A systematic benchmark of the ab initio Bethe-Salpeter equation approach for low-lying optical excitations of small organic molecules
Fabien Bruneval, Samia M. Hamed, Jeffrey B. Neaton
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 funct…
