Query: The parity effect in Josephson junction arrays   We study the parity effect and transport due to quasiparticles in circuits
comprised of many superconducting islands. We develop a general approach and
show that it is equivalent to previous methods for describing the parity effect
in their more limited regimes of validity. As an example we study transport
through linear arrays of Josephson junctions in the limit of negligible
Josephson energy and observe the emergence of the parity effect with decreasing
number of non-equilibrium quasiparticles. Due to the exponential increase in
the number of relevant charge states with increasing length, in multi-junction
arrays the parity effect manifests in qualitatively different ways to the two
junction case. The role of charge disorder is also studied as this hides much
of the parity physics which would otherwise be observed. Nonetheless, we see
that the current through a multi-junction array at low bias is limited by the
formation of meta-stable even-parity states.
