Modern electronic and optoelectronic devices are approaching nanometric dimensions
where microscopic details cannot be treated in an effective way. Atomistic approaches …

This review seeks to extend the scope of both the experimental and theoreticalwork carried
out since I completed my 1993 review on the electronic, optical, andto a lesser extent, the …

Progress in nanoscience is becoming increasingly dependent on simulation and modelling.
This is due to a combination of three factors: the reduced size of nano-objects, the …

We present a pseudopotential approach to the calculation of the excitonic spectrum of
semiconductor quantum dots. Starting from a many-body expansion of the exciton wave …

Colloidal semiconductor nanocrystals become increasingly important in materials science
and technology, due to their optoelectronic properties that are tunable by size. The …

An exciton evolving from an m-fold degenerate hole level and an n-fold degenerate electron
level has a nominal m× n degeneracy, which is often removed by electron− hole …

We present an approach to calculate the excitonic fine-structure splittings due to electron-
hole short-range exchange interactions using the local-density approximation …

Electron-hole exchange interactions can lead to spin-forbidden “dark” excitons in direct-gap
quantum dots. Here, we explore an alternative mechanism for creating optically forbidden …

Relativistic effects are of major importance for understanding the properties of heavier atoms
and molecules. Volumes I-III of Relativistic Theory of Atoms and Molecules constitute the …

The quantal confinement present in nanoscaled semiconductor crystals gives rise to
dramatic changes in their optical properties, 1, 2 and especially in their exciton fine structure …
