Abstract
We work out the phase diagram of an array of Josephson junctions with quasiparticle tunneling, taking into account the quasiparticle-pair interference term (QPPI). Besides introducing interesting renormalization effects in the Josephson term, the QPPI shifts the critical resistance. At finite temperatures a proper treatment of tunneling effects leads to reentrant behavior.
