Exact analytical solutions describing quantum dot, ring and wire wavefunctions
Jacky Even,S Loualiche +1 more
TL;DR: In this article, exact analytical solutions of electronic wavefunctions in quantum ring-like structures are found using a symmetry-adapted coordinate system, in the case of an infinite potential barrier, it is related to a more general problem of finding resonance modes in a ringlike cavity.

Effects of quantum size and potential shape on the spectra of an electron and a donor in quantum dots
TL;DR: In this paper, the potential-shape, quantum size, and donor position effects on the level ordering and binding of quantum dots with different confinement potentials are studied in detail, which may be useful for understanding physical phenomena and designing materials and devices in quantum-dot structures.

Controlling orbital collapse from inside and outside a transition element
TL;DR: In this article, a study of the bimodal behaviour of atomic wavefunctions for a transition element (Cr) and how this behaviour can be controlled and even turned into single-mode character either by varying the effective nuclear charge for nonintegral values, or placing the atom in a spherical cavity of adjustable radius.
