Our recent work on the electronic and optical properties of semiconductor and graphene
quantum dots is reviewed. For strained self-assembled InAs quantum dots on GaAs or InP …

We report on the optical spectroscopy of a single InAs/GaAs quantum dot doped with a
single Mn atom in a longitudinal magnetic field of a few Tesla. Our findings show that the Mn …

Strong Coulomb correlations together with multi-valley electronic bands in the presence of
spin-orbit interaction are at the heart of studies of the rich physics of excitons in monolayers …

Here we demonstrate, for the first time, violation of Bell's inequality using a triggered
quantum dot photon-pair source without post-selection. Furthermore, the fidelity to the …

A promising method to investigate dark exciton transitions in quantum dots is presented. The
optical recombination of the dark exciton is allowed when the exciton state is coupled with …

We report on a systematic correlation between the fine-structure splitting and polarization
anisotropy of excitons in InAs/GaAs quantum dots, but with an unexpected reversal in order …

Single GaN/Al (Ga) N quantum dots (QDs) have been investigated by means of
microphotoluminescence. Emission spectra related to excitons and biexcitons have been …

We present a comprehensive photoluminescence study of the exchange interaction in self-
assembled CdTe/ZnTe quantum dots. We exploit the presence of multiple charge states in …

We use nominally spheroidal CdSe nanocrystals with a zinc blende crystal structure to study
how shape perturbations lift the energy degeneracies of the band-edge exciton …

We study the biexciton formation process in a single CdTe/ZnTe quantum dot. Consistently
with previous studies, we find subquadratic dependence of the biexciton photoluminescence …
