Ground-state degeneracies leave recognizable topological scars in the one-particle density
In Kohn-Sham density functional theory (KS-DFT) a fictitious system of non-interacting particles is constructed having the same ground-state (GS) density as the physical system of interest.

ABSTRACT Understanding aromaticity in excited states remains a fundamental challenge in chemistry. Baird aromaticity describes the stabilization of a molecule's lowest triplet excited state due to cyclic conjugation, similar to how Huckel's rule applies to the ground state.

Fundamental building blocks of eumelanins: electronic properties of indolequinone-dimers
We present results from the theoretical INDO calculations of the electronic structure for stacked eumelanins' monomers. As basic indolic components of the eumelanin structure 5,6-dihydroxyindole (DHI or HQ) and its oxidized forms (SQ and IQ) were chosen.

Evolution of structural motifs of transition metal systems from tetramers and hexamers to bulk phases is studied. Clusters of transition metal (TM) elements are becoming increasingly important in our daily lives for a wide ensemble of applications in catalysis and bio‐fields, for health, energy and environmental problems.

A Critical Assessment of the Performance of Magnetic and Electronic Indices of Aromaticity [PDF]
The lack of reference aromatic systems in the realm of inorganic aromatic compounds makes the evaluation of aromaticity in all-metal and semimetal clusters a difficult task.
