The parity effect in a Jospehson junction arrayJared Cole1, Andreas Heimes2, and •Michael Marthaler21Chemical and Quantum Physics, School of Applied Sciences, RMIT University, Melbourne, Victoria 3001, Australia — 2Institut für Theoretische Festkörperphysik, Karlsruhe Institute of Technology, 76128 Karlsruhe, Germany

We study transport in a Josephson junction array for small Josephson energies. For very small Josephson energy the transport is dominated by single quasiparticle tunneling. We consider a regime where there is enough energy to inject quasiparticles by breaking a cooper-pair, but transport inside of the array is dominated by the parity effect. This means that the current is caried by a small number of quasiparticles above the gap. We observer the crossover temperature T*, which is also known from parity experiments in superconducting single electron transistors.
