Temporal dynamics of a chain of Josephson junctions in the Coulomb blockade regime. — •Jared Cole and Michael Marthaler — Institut für Theoretische Festkörperphysik, Karlsruher Institut für Technologie, Karlsruhe, Germany

Recent experiments have studied the transport of individual charge carriers through a one-dimensional array of small Josephson junctions, in the limit of small Josephson coupling. Modern time resolved charge detection techniques allow the direct measurement of temporal correlations between these carriers. We study such a system theoretical with the aim of understanding the transport properties within the array, in both the normal and superconducting regimes. Of particular interest are the effects of Coulomb repulsion between the carriers and the resulting transport through the array.
