Stochastic density functional theory [PDF]

open access: yesWIREs Computational Molecular Science, 2018
Linear-scaling implementations of density functional theory (DFT) reach their intended efficiency regime only when applied to systems having a physical size larger than the range of their Kohn-Sham density matrix (DM).

Implicit Density Functional Theory [PDF]

open access: yesPhysical Review A, 2006
A fermion ground state energy functional is set up in terms of particle density, relative pair density, and kinetic energy tensor density. It satisfies a minimum principle if constrained by a complete set of compatibility conditions. A partial set, which

Nuclear fission in covariant density functional theory

open access: yesEPJ Web of Conferences, 2013
The current status of the application of covariant density functional theory to microscopic description of nuclear fission with main emphasis on superheavy nuclei (SHN) is reviewed.

Density functional versus spin-density functional and the choice of correlated subspace in multi-variable effective action theories of electronic structure [PDF]

open access: yesarXiv, 2015
Modern extensions of density functional theory such as the density functional theory plus U and the density functional theory plus dynamical mean-field theory require choices, including selection of variable (charge vs spin density) for the density functional and specification of the correlated subspace.

Multilevel Density Functional Theory [PDF]

open access: yesJournal of Chemical Theory and Computation, 2021
We introduce a novel density-based multilevel approach in density functional theory. In this multilevel density functional theory (MLDFT), the system is partitioned in an active and an inactive fragment, and all interactions are retained between the two parts.

The central role of density functional theory in the AI age [PDF]

open access: yesScience, 2023
Density functional theory (DFT) plays a pivotal role in chemical and materials science because of its relatively high predictive power, applicability, versatility, and computational efficiency.

Density-functional theory on graphs [PDF]

open access: yesThe Journal of Chemical Physics, 2021
The principles of density-functional theory are studied for finite lattice systems represented by graphs. Surprisingly, the fundamental Hohenberg–Kohn theorem is found void, in general, while many insights into the topological structure of the density-potential mapping can be won.

Density functional theory [PDF]

open access: yesPhotosynthesis Research, 2009
Density functional theory (DFT) finds increasing use in applications related to biological systems. Advancements in methodology and implementations have reached a point where predicted properties of reasonable to high quality can be obtained. Thus, DFT studies can complement experimental investigations, or even venture with some confidence into ...

Improving Results by Improving Densities: Density-Corrected Density Functional Theory. [PDF]

open access: yesJournal of the American Chemical Society, 2022
Density functional theory (DFT) calculations have become widespread in both chemistry and materials, because they usually provide useful accuracy at much lower computational cost than wavefunction-based methods.
