Singlet vs. triplet interelectronic repulsion in confined atoms
(Elsevier, 2018)
Hund’s multiplicity rule invariably holds for the ground configurations of few-electron atoms as well as those of multi-electron quantum dots. However, the ordering of the corresponding interelectronic repulsions exhibits ...
Quantum defect asymptotics at the critical charge: A study of the integrality conjecture
(Elsevier, 2018)
A single (n, ℓ) electron outside an (N −1)-electron atomic core is bound as long as Z > Zc = N − 1. A conjecture is examined, according to which the quantum defect of the outermost electron satisfies limZ!Zc δn,ℓ(Z) = Nℓ, ...
