Moreau-Yosida-based Kohn-Sham Inversion for Periodic Systems

Vebjørn H. Bakkestuen, Michael F. Herbst, Vegard Falmår +2

Density-potential inversion for periodic systems within Moreau-Yosida-regularised density-functional theory is investigated, both theoretically and numerically. We develop the fram…

Coupled-Cluster Theory Revisited. Part II: Analysis of the single-reference Coupled-Cluster equations

Mihály A. Csirik, Andre Laestadius

In a series of two articles, we propose a comprehensive mathematical framework for Coupled-Cluster-type methods. In this second part, we analyze the nonlinear equations of the sing…

Coupled-Cluster Theory Revisited. Part I: Discretization

Mihály A. Csirik, Andre Laestadius

In a series of two articles, we propose a comprehensive mathematical framework for Coupled-Cluster-type methods. These methods aim at accurately solving the many-body Schrodinger e…

Analysis of The Tailored Coupled-Cluster Method in Quantum Chemistry

Fabian M. Faulstich, Andre Laestadius, Örs Legeza +2

In quantum chemistry, one of the most important challenges is the static correlation problem when solving the electronic Schrödinger equation for molecules in the Born--Oppenheimer…

Analysis of the Extended Coupled-Cluster Method in Quantum Chemistry

Andre Laestadius, Simen Kvaal

The mathematical foundation of the so-called extended coupled-cluster method for the solution of the many-fermion Schrödinger equation is here developed. We prove an existence and…
