We investigate experimentally and theoretically few-particle effects in the optical spectra of
single quantum dots (QDs). Photodepletion of the QD together with the slow hop** …

We propose an all-optical implementation of quantum-information processing in
semiconductor quantum dots, where electron-hole excitations (excitons) serve as the …

A review of coherent phenomena in photoexcited semiconductors is presented. In particular,
two classes of phenomena are considered. The first is concerned with the role played by …

We perform ab initio calculations of optical properties for a typical semiconductor conjugated
polymer, poly-para-phenylenevinylene, in both isolated chain and crystalline packing. In …

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 …

The optical properties of high-quality V-groove GaAs/Al x Ga 1− x As quantum wires have
been investigated using low-temperature photoluminescence (PL) and photoluminescence …

In this paper we present a review on major advances achieved over the past ten years in the
field of fabrication of semiconductor quantum wires (QWRs) using epitaxial growth …

In the present work, We calculate the donor binding energy for a V-groove GaAs/AlxGa1−
xAs quantum wire using a variational procedure within the effective mass approximation. We …

We use in this paper the variational method to calculate the polarizability of a hydrogenic
donor impurity, in the presence of electric field, in a V-groove GaAs/AlxGa1− xAs quantum …

The crystal-induced energy splitting of the lowest excitonic state in polymer crystals, the so-
called Davydov splitting Δ, is calculated with a first-principles density-matrix scheme. We …
