Combining Density Functional Theory and Density Matrix Functional Theory [PDF]

open access: yesPhysical Review A, 2010
We combine density-functional theory with density-matrix functional theory to get the best of both worlds. This is achieved by range separation of the electronic interaction which permits to rigorously combine a short-range density functional with a long-range density-matrix functional.

Density functional theory: An introduction [PDF]

open access: greenAmerican Journal of Physics, 2000
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

Perspective on density functional theory [PDF]

open access: yesThe Journal of Chemical Physics, 2012
Density functional theory (DFT) is an incredible success story. The low computational cost, combined with useful (but not yet chemical) accuracy, has made DFT a standard technique in most branches of chemistry and materials science.

Nuclear density functional theory [PDF]

open access: yesAdvances in Physics: X, 2020
The goal of nuclear structure physics is to provide a complete understanding of the static properties of atomic nuclei, their excitation spectra, their response to external fields and their decays.

Entropic Density Functional Theory

open access: yesEntropy, 2023
A formulation of density functional theory (DFT) is constructed as an application of the method of maximum entropy for an inhomogeneous fluid in thermal equilibrium. The use of entropy as a systematic method to generate optimal approximations is extended

From Density Functional Theory to Conceptual Density Functional Theory and Biosystems

open access: yesPharmaceuticals, 2022
The position of conceptual density functional theory (CDFT) in the history of density functional theory (DFT) is sketched followed by a chronological report on the introduction of the various DFT descriptors such as the electronegativity, hardness ...

Current Densities in Density Functional Theory [PDF]

open access: yesPhysical Review A, 2013
It is well known that any given density rho(x)can be realized by a determinantal wave function for N particles. The question addressed here is whether any given density rho(x) and current density j(x) can be simultaneously realized by a (finite kinetic ...

Spin in Density-Functional Theory [PDF]

open access: yesInternational Journal of Quantum Chemistry, 2012
The accurate description of open-shell molecules, in particular of transition metal complexes and clusters, is still an important challenge for quantum chemistry.

Density functional theory of electrowetting [PDF]

open access: yesPhysical Review E, 2014
The phenomenon of electrowetting, i.e., the dependence of the macroscopic contact angle of a fluid on the electrostatic potential of the substrate, is analyzed in terms of the density functional theory of wetting.

Pair densities in density functional theory [PDF]

open access: yesMultiscale Modeling & Simulation, 2015
The exact interaction energy of a many-electron system is determined by the electron pair density, which is not well-approximated in standard Kohn-Sham density functional models.
