How accurate are TD‐DFT excited‐state geometries compared to DFT ground‐state geometries?
In this work, we take a different angle to the benchmarking of time‐dependent density functional theory (TD‐DFT) for the calculation of excited‐state geometries by extensively assessing how accurate such geometries are compared to ground‐state geometries

Gauged Double Field Theory [PDF]
We find necessary and sufficient conditions for gauge invariance of the action of Double Field Theory (DFT) as well as closure of the algebra of gauge symmetries. The so-called weak and strong constraints are sufficient to satisfy them, but not necessary.

Partition-DFT on the water dimer [PDF]
As is well known, the ground-state symmetry group of the water dimer switches from its equilibrium Cs-character to C2h-character as the distance between the two oxygen atoms of the dimer decreases below RO–O∼2.5 Å. For a range of RO–O between 1 and 5 Å, and for both symmetries, we apply Partition Density Functional Theory (PDFT) to find the unique ...

Type II DFT solutions from Poisson–Lie $T$-duality/plurality [PDF]
String theory has $T$-duality symmetry when the target space has Abelian isometries. A generalization of $T$-duality, where the isometry group is non-Abelian, is known as non-Abelian $T$-duality, which works well as a solution-generating technique in ...

Quantum chemical study of NO reduction mechanism on Ag /Al2O3 catalysts
It was shown that N2O content among NO reduction products increases with an increase of the silver concentration in the catalyst because the nature of the catalytic centers changes and leads to a subsequent change in the mechanism of the reaction.

A New View on Density Corrected DFT: Can One Get a Better Answer for a Good Reason? [PDF]
Despite its widespread use, density functional theory (DFT) has several notable areas of failure; perhaps the most well-studied of these failures is self-interaction error (SIE). Density corrected DFT (DC-DFT) was proposed as a potential solution to systems where SIE causes traditional DFT to fail.

Density Functional Theory Approach to Noncovalent Interactions via Interacting Monomer Densities [PDF]
A recently proposed "DFT+dispersion" treatment (Rajchel et al., Phys. Rev. Lett., 2010, 104, 163001) is described in detail and illustrated by more examples. The formalism derives the dispersion-free density functional theory (DFT) interaction energy and

Periodic DFT Calculations—Review of Applications in the Pharmaceutical Sciences
In the introduction to this review the complex chemistry of solid-state pharmaceutical compounds is summarized. It is also explained why the density functional theory (DFT) periodic calculations became recently so popular in studying the solid APIs ...
