Generic size dependences of pairing in ultrasmall systems: electronic nano-devices and atomic nuclei

Average, global pairing behaviours of electronic devices, like films, wires, and grains are studied with semiclassical methods, as Weyl and Thomas-Fermi approximations, in the ultrasmall, i.e., quantal regime, which exhibits strong quantum fluctuations and shell effects. This is the case also for superfluid nuclei. Results, mostly analytic, are elaborated for average size dependences, ready for easy use also in other circumstances. Comparisons with experimental results are given where possible.
