TL;DR: Dalton is a powerful general‐purpose program system for the study of molecular electronic structure at the Hartree–Fock, Kohn–Sham, multiconfigurational self‐consistent‐field, Møller–Plesset, configuration‐interaction, and coupled‐cluster levels of theory.
Journal ArticleDOI
X-ray Emission Spectroscopy Evidences a Central Carbon in the Nitrogenase Iron-Molybdenum Cofactor
Kyle M. Lancaster,Michael Roemelt,Patrick Ettenhuber,Yilin Hu,Markus W. Ribbe,Frank Neese,Frank Neese,Uwe Bergmann,Serena DeBeer,Serena DeBeer +9 more
TL;DR: A central light atom in a cofactor at the nitrogenase active site is identified as a carbon, indicating that among the candidate atoms oxygen, nitrogen, and carbon, it is carbon that best fits the XES data.
Journal ArticleDOI
Linear-Scaling Coupled Cluster with Perturbative Triple Excitations: The Divide-Expand-Consolidate CCSD(T) Model.
Janus J. Eriksen,Pablo Baudin,Patrick Ettenhuber,Kasper Kristensen,Thomas Kjærgaard,Poul Jørgensen +5 more
TL;DR: A reformulation of the traditional (T) triples correction to the coupled cluster singles and doubles (CCSD) energy in terms of local Hartree-Fock (HF) orbitals such that its structural form aligns with the recently developed linear-scaling divide-expand-consolidate (DEC) coupled cluster family of local correlation methods.
Journal ArticleDOI
Efficient linear-scaling second-order Møller-Plesset perturbation theory: The divide-expand-consolidate RI-MP2 model.
TL;DR: The errors associated with the RI and DEC approximations are compared, and it is shown that the DEC-RI-MP2 method can be applied to systems far beyond the ones that can be treated with a conventional RI- MP2 implementation.
Journal ArticleDOI
The divide–expand–consolidate MP2 scheme goes massively parallel
Kasper Kristensen,Thomas Kjærgaard,Ida-Marie Høyvik,Patrick Ettenhuber,Poul Jørgensen,Branislav Jansík,Simen Reine,Jacek Jakowski +7 more
TL;DR: A massively parallel algorithm for calculating MP2 energies and densities using the divide–expand–consolidate scheme where a calculation on a large system is divided into many small fragment calculations employing local orbital spaces, which is highly suited for large super computer architectures.
