Single-particle-exact density functional theory
Martin-Isbjörn Trappe, Jun Hao Hue, Jonah Huang Zi Chao +4
We introduce 'single-particle-exact density functional theory' (1pEx-DFT), a novel density functional approach that represents all single-particle contributions to the energy with…
Contactium: A strongly correlated model system
Jerzy Cioslowski, Berthold-Georg Englert, Martin-Isbjörn Trappe +1
At the limit of an infinite confinement strength , the ground state of a system that comprises two fermions or bosons in a harmonic confinement interacting through the Fermi--Hu…
1-matrix functional for long-range interaction energy of two hydrogen atoms
Jerzy Cioslowski, Christian Schilling, Rolf Schilling
The leading terms in the large- asymptotics of the functional of the one-electron reduced density matrix for the ground-state energy of the H molecule with the internuclear…
Robust Validation Of Approximate 1-Matrix Functionals With Few-Electron Harmonium Atoms
Jerzy Cioslowski, Mario Piris, Eduard Matito
A simple comparison between the exact and approximate correlation components U of the electron-electron repulsion energy of several states of few-electron harmonium atoms with vary…
