Density-potential inversion from Moreau-Yosida regularization
Penz, Markus; Csirik, Mihaly Andras; Laestadius, Andre (Peer reviewed; Journal article, 2023) -
Exchange energies with forces in density-functional theory
Tancogne-Dejean, Nicolas; Penz, Markus; Laestadius, Andre; Csirik, Mihaly Andras; Ruggenthaler, Michael; Rubio, Angel (Peer reviewed; Journal article, 2024)We propose exchanging the energy functionals in ground-state density-functional theory with physically equivalent exact force expressions as a new promising route toward approximations to the exchange–correlation potential ... -
Exchange-only virial relation from the adiabatic connection
Laestadius, Andre; Csirik, Mihaly Andras; Penz, Markus; Tancogne-Dejean, Nicolas; Ruggenthaler, Michael; Rubio, Angel; Helgaker, Trygve (Peer reviewed; Journal article, 2024)The exchange-only virial relation due to Levy and Perdew is revisited. Invoking the adiabatic connection, we introduce the exchange energy in terms of the right-derivative of the universal density functional w.r.t. the ... -
The structure of the density-potential mapping Part I: Standard density-functional theory
Penz, Markus; Tellgren, Erik Ingemar; Csirik, Mihaly Andras; Ruggenthaler, Michael; Laestadius, Andre (Peer reviewed; Journal article, 2023) -
The Structure of the Density-Potential Mapping. Part II: Including Magnetic Fields
Penz, Markus; Tellgren, Erik Ingemar; Csirik, Mihaly Andras; Ruggenthaler, Michael; Laestadius, Andre (Peer reviewed; Journal article, 2023)The Hohenberg−Kohn theorem of density-functional theory (DFT) is broadly considered the conceptual basis for a full characterization of an electronic system in its ground state by just one-body particle density. In this ... -
