Abstract
We have investigated proximity-induced supercurrents in single-walled carbon nanotubes in the Kondo regime and compared them with supercurrents obtained on the same tube with Fabry-P\'erot resonances. Our data display a wide distribution of Kondo temperatures ${T}_{K}=1--14\text{ }\text{K}$, and the measured critical current ${I}_{\text{CM}}$ vs ${T}_{K}$ displays two distinct branches; these branches, distinguished by zero-field splitting of the normal-state Kondo conductance peak, differ by an order of magnitude at large values of ${T}_{K}$. Evidence for renormalization of Andreev levels in Kondo regime is also found.
