Thesis Project :
"Investigation of heat transport effects in hybrid superconducting devices"

The research project is targeted to the experimental study of heat transport effects in hybrid superconducting structures involving nanowires. The main focus will be on nanodevices implemented with nanowires, both semiconducting and metallic, coupled to superconducting electrodes.
The aim of the research project is twofold. On one side we will investigate electronic cooling in superconductor refrigerators with the goal of extending the existing coolers technology to semiconducting nanowires, as well as we will realize integrated multistage coolers which might allow to refrigerate electrons from temperatures above 1k down to the mK regime.
On the other side, the other goal of the research project is to investigate the role of coherence on heat transport in such hybrid superconducting nanostructures, in particular in the presence of proximity effect. This would lead to a deeper understanding of the impact of correlations on heat transport, and might enable the coherent manipulation of heat flow in nanosystems.
The samples will be investigatedat very low temperatures (down to 50 mK or below) also in the presence of magnetic field. The low temperature transport measurements will allow to demosntrate electron cooling in such nanodevices, as well as coherent control of heat which is intrinsic to the nature of these systems.
