Density Functional Theory -- an introduction [PDF]

open access: yes, 1998
Density Functional Theory (DFT) is one of the most widely used methods for "ab initio" calculations of the structure of atoms, molecules, crystals, surfaces, and their interactions. Unfortunately, the customary introduction to DFT is often considered too

LOBSTER: Local orbital projections, atomic charges, and chemical‐bonding analysis from projector‐augmented‐wave‐based density‐functional theory

open access: yesJournal of Computational Chemistry, 2020
We present an update on recently developed methodology and functionality in the computer program Local Orbital Basis Suite Toward Electronic‐Structure Reconstruction (LOBSTER) for chemical‐bonding analysis in periodic systems.

Machine learning and density functional theory [PDF]

open access: yesNature Reviews Physics, 2022
Over the past decade machine learning has made significant advances in approximating density functionals, but whether this signals the end of human-designed functionals remains to be seen.

Periodic subsystem density-functional theory [PDF]

open access: yesThe Journal of Chemical Physics, 2014
By partitioning the electron density into subsystem contributions, the Frozen Density Embedding (FDE) formulation of subsystem Density Functional Theory (DFT) has recently emerged as a powerful tool for reducing the computational scaling of Kohn–Sham DFT. To date, however, FDE has been employed to molecular systems only.

Density functional theory, chemical reactivity, and the Fukui functions

open access: yesFoundations of Chemistry: Philosophical, Historical, Educational and Interdisciplinary Studies of Chemistry, 2022
We review the early works which were precursors of the Conceptual Density Functional Theory. Starting from Thomas–Fermi approximation and from the exact formulation of Density Functional Theory by Hohenberg and Kohn’s theorem, we will introduce ...

Current-density functional theory for bosonic superfluids

open access: yesJournal of Physics Communications, 2023
A finite-temperature current-density functional theory for bosonic superfluids (sf-CDFT) in the thermal equilibrium state is proposed herein. In the sf-CDFT, hydrodynamic physical quantities, such as particle number density, current density, and the ...
