eT 2.0: An efficient open-source molecular electronic structure program
Sarai Dery Folkestad, Eirik F. Kjønstad, Alexander C. Paul +34
The eT program is an open-source electronic structure program with emphasis on performance and modularity. As its name suggests, the program features extensive coupled cluster capa…
Automatic generation of density fitting auxiliary basis sets for all electron Dirac-Kohn-Sham calculations
Nicolo' Antonini, Enrico Ronca, Loriano Storchi +1
In this study, we present a general workflow that enables the automatic generation of auxiliary density basis sets for all elements of the periodic table (from H to Og) to facilita…
A Complete Active Space Self-Consistent Field approach for molecules in QED environments
Riccardo Alessandro, Matteo Castagnola, Henrik Koch +1
Multireference systems are usually challenging to investigate using ab initio methods as they require an accurate description of static electron correlation. The urgency of develop…
Strong coupling quantum electrodynamics Hartree-Fock response theory
Matteo Castagnola, Rosario R. Riso, Yassir El Moutaoukal +2
The development of reliable ab initio methods for light-matter strong coupling is necessary for a deeper understanding of molecular polaritons. The recently developed strong coupli…
Strong coupling Møller-Plesset perturbation theory
Yassir El Moutaoukal, Rosario R. Riso, Matteo Castagnola +2
Perturbative approaches are methods to efficiently tackle many-body problems, offering both intuitive insights and analysis of correlation effects. However, their application to sy…
