The authors review the physics of ultrafast dynamics in semiconductors and their
heterostructures, including both the observed experimental phenomena and the theoretical …

We present a new high performance configuration interaction code optimally designed for
the calculation of the lowest-energy eigenstates of a few electrons in semiconductor …

The electron and hole addition energies, the quasiparticle gap, and the optical gap of InAs,
InP, and Si quantum dots are calculated using microscopic pseudopotential wave functions …

A detailed analysis of the electro-optical response of single as well as coupled
semiconductor quantum dots is presented. This is based on a realistic—ie, fully …

We study the energy spectra of small three-dimensional (3D) and two-dimensional (2D)
semiconductor quantum dots through different theoretical approaches (single-site Hubbard …

In this article we review the physical characteristics of quantum cascade transitions (QCTs)
in various nanoscopic systems. The quantum cascade laser which utilizes such transitions in …

The ground state structure of few-electron concentric double quantum rings is investigated
within the local spin density approximation. Signatures of inter-ring coupling in the addition …

Three-dimensional confinement in semiconductor quantum dots results in a discrete energy
spectrum for charge carriers. This chapter shows that maximal spin alignment still consistent …

We study coupled semiconductor quantum dots theoretically through a generalized Hubbard
approach, where intra-and inter-dot Coulomb correlation, as well as tunneling effects are …

A potential implementation of quantum-information schemes in semiconductor
nanostructures is studied. To this end, the formal theory of quantum encoding for avoiding …
