Abstract
Superconductivity in nanowires made of weak coupling superconductor materials is investigated using a Green function approach. We show that these are multigap systems in which the ratio Δ(T)/kBTc is to a large extent similar to what is observed in some high-Tc two-gap systems, such as MgB2 and some of the Fe-based superconductors. On the other hand, because of confinement, the superfluid density has a temperature behavior of the form ns(T)=1−(T/Tc)3 near Tc, thus deviating from the BCS behavior for bulk superconductors.
