We demonstrate the optical addressability of the spin of an individual chromium atom (Cr)
embedded in a semiconductor quantum dot. The emission of Cr-doped quantum dots and …

The control of single spins in solids is a key but challenging step for any spin-based solid-
state quantumcomputing device. Thanks to their expected long coherence time, localized …

In the framework of the effective mass approximation the biexciton states have been
investigated in the oblate and prolate ellipsoidal quantum dots. To calculate the ground state …

We study a diluted magnetic semiconductor system based on the spin of the ionized
acceptor Cr+. We show that the negatively charged Cr+ ion, an excited state of the Cr in II-VI …

We report on the coherent dynamics of the spin of an individual magnetic atom coupled to
carriers in a semiconductor quantum dot which has been investigated by resonant …

We report on the spin properties of individual Mn atoms in strain-free quantum dots. The
quantum dots are formed by width fluctuations in a thin CdTe/(Cd, Mg) Te quantum-well …

A theoretical study of the effect of hydrostatic pressure on the binding energy of shallow
hydrogenic impurity in a cylindrical quantum dot (QD) using a variational approach within …

We demonstrate optical spin orientation of an individual Mn 2+ ion embedded in a
CdSe/ZnSe quantum dot. It is achieved through the injection of spin-polarized excitons to the …

Using the emission of the positively charged exciton as a probe, we analyze the dynamics of
the optical pumping and the dynamics of the relaxation of a Mn spin exchange coupled with …

We study the dynamics of the spin system that consists of a positively charged II-VI
semiconductor quantum dot doped with a single Cr+ ion. The resonant photoluminescence …
