Observation of shot-noise-induced asymmetry in the Coulomb blockaded Josephson junction
arXiv:cond-mat/0403427 · doi:10.1103/PhysRevLett.93.197002
Abstract
We have investigated the influence of shot noise on the IV-curves of a single mesoscopic Josephson junction. We observe a linear enhancement of zero-bias conductance of the Josephson junction with increasing shot noise power. Moreover, the IV-curves become increasingly asymmetric. Our analysis on the asymmetry shows that the Coulomb blockade of Cooper pairs is strongly influenced by the non-Gaussian character of the shot noise.
