Solotronics, optoelectronics based on solitary dopants, is an emerging field of research and
technology reaching the ultimate limit of miniaturization. It aims at exploiting quantum …

Impurity doping can be used to dramatically alter the physical properties of semiconductor
nanostructures and endow them with promising new technological potential. This review …

Single impurities with nonzero spin and multiple ground states offer a degree of freedom that
can be utilized to store the quantum information. However, Fe2+ dopant is known for having …

In the present work we propose that two-time correlations of Majorana edge localized
fermions constitute a novel and versatile toolbox for assessing the topological phases of one …

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 …

We report evidence of a photoinduced coupling between two spins provided by Mn dopants
in<? format?> their neutral acceptor state A 0 in a single InAs/GaAs quantum dot. The …

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 …

When a Co 2+ impurity is embedded in a semiconductor structure, crystal strain strongly
influences the zero-field splitting between Co 2+ states with spin projection S z=±3/2 and S …

Optical pump-probe experiments reveal spin beats of manganese ions in (Cd, Mn) Te, due
to hyperfine and crystal fields. At “magic” orientations of the magnetic field, the effect of local …
