Use of Cholesky decomposition in the CFOUR program package
Jürgen Gauss, Simon Blaschke, Sophia Burger +10
An overview is given about our efforts to speed up high-level computations of molec- ular energies and properties using Cholesky decomposition (CD). We describe the cor- responding…
Exploitation of complex Abelian point groups in quantum-chemical calculations
Marios-Petros Kitsaras, Stella Stopkowicz
Quantum-chemical calculations often make use of point-group theory to exploit molecular symmetry, resulting in a reduction of the computational cost and in insights into the electr…
Connection between and Extended Coupled Cluster
Johannes Tölle, Marios-Petros Kitsaras, Andreas Irmler +2
Coupled-cluster (CC) theory and Green's function many-body perturbation theory (MBPT) have long evolved as distinct yet complementary frameworks for describing electronic correlati…
Analytic gradients based on a double-similarity transformation equation-of-motion coupled-cluster treatment
Marios-Petros Kitsaras, Johannes Tölle, Pierre-François Loos
The accurate prediction of ionization potentials (IPs) is central to understanding molecular reactivity, redox behavior, and spectroscopic properties. While vertical IPs can be acc…
Unitary Coupled-Cluster theory for the treatment of molecules in strong magnetic fields
Laura Grazioli, Marios-Petros Kitsaras, Stella Stopkowicz
In Coupled-Cluster (CC) theory, unphysical complex energies may arise in the presence of strong magnetic fields, near conical intersections, or in systems exhibiting complex Abelia…
Fully Analytic Nuclear Gradients for the Bethe--Salpeter Equation
Johannes Tölle, Marios-Petros Kitsaras, Pierre-François Loos
The Bethe-Salpeter equation (BSE) formalism, combined with the approximation for ionization energies and electron affinities, is emerging as an efficient and accurate method f…
