ABSTRACT:
Superconductivity is a peculiar state of matter which is manifested in such diverse fields as solid state physics, nuclear physics, astrophysics, biology, etc. In this talk we focus on small metallic nanoclusters (N 102-103 where N is the number of free carriers) which contain delocalized electrons. These electrons form shells similar to those in atoms or nuclei. It turns out that under special, but perfectly realistic conditions, superconducting pairing is very strong and can lead to high values of Tc. We have shown that for realistic sets of parameters one can observe very high values of Tc (Tc 102 K ) as well as a strong modification of the energy spectrum. Nanoclusters should form a new family of high temperature superconductors and in principle, it should be possible to raise Tc up to room temperature. We have proposed specific experiments aimed at detecting this phenomenon (e.g. spectroscopy and magnetic properties). This phenomenon is quite promising for the creation of high Tc superconducting tunneling networks.
