A Chemist's Guide to Density Functional Theory

open access: yes, 2000
"Chemists familiar with conventional quantum mechanics will applaud and benefit greatly from this particularly instructive, thorough and clearly written exposition of density functional theory: its basis, concepts, terms, implementation, and performance ...

Repulsively diverging gradient of the density functional in the reduced density matrix functional theory

open access: yesNew Journal of Physics, 2021
The reduced density matrix functional theory (RDMFT) is a remarkable tool for studying properties of ground states of strongly interacting quantum many body systems.

The local density approximation in density functional theory [PDF]

open access: yesPure and Applied Analysis, 2020
We give the first mathematically rigorous justification of the Local Density Approximation in Density Functional Theory. We provide a quantitative estimate on the difference between the grand-canonical Levy-Lieb energy of a given density (the lowest possible energy of all quantum states having this density) and the integral over the Uniform Electron ...

Density-functional fluctuation theory of crowds

open access: yesNature Communications, 2018
Tools from statistical physics can be used to investigate a large variety of fields ranging from economics to biology. Here the authors first adapt density-functional theory to predict the distributions of crowds in new environments and then validate ...

Investigation of structure and vibrational properties of cyclobutane pirimidine dimer [PDF]

open access: yesHemijska Industrija, 2013
We performed a theoretical analysis of the structure and vibrational properties of cyclobutane pyrimidine dimer, which is the main product in a photochemical reaction involving two molecules of 1-methylthymine.

Electronic structure of CeAuAl$_3$ using density functional theory

open access: yesSciPost Physics Proceedings, 2023
We studied the magnetic properties and electronic structure of $CeAuAl_3$ using density functional theory. This compound shows a large Sommerfeld coefficient, a Kondo temperature, ${T_K=4\,K}$ and antiferromagnetic order below ${T_N=1.1\,K}$.

Thirty years of density functional theory in computational chemistry: an overview and extensive assessment of 200 density functionals

open access: yes, 2017
In the past 30 years, Kohn–Sham density functional theory has emerged as the most popular electronic structure method in computational chemistry. To assess the ever-increasing number of approximate exchange-correlation functionals, this review benchmarks
