This research focus in quantum computing techniques, and how to use ab-initio tools, tight-binding, and many-body correlated states computations to understand the electrical and optical properties of QDs and nanostructures for technological applications. The trainees will be able to anchor their training in Auger processes in nanocrystals and self-assembled quantum dots to name a few. QMs are often ‘heterogeneous’, i.e. either they completely lack long-range order and have the same key features as crystalline materials only at medium or short length scales, or they contain partial low symmetry environment, due to imperfections, which often define and affect the electronic/photonic quantum phenomena such as coherence, interaction, entanglement, and topological effects.
