The transport properties of two-dimensional arrays of small Josephson junctions shunted with ohmic resistors are investigated. The zero-temperature phase diagram shows a phase transition driven by quantum fluctuations and dissipation. The recovery of Josephson-like current by the dissipation is disc
A detailed treatment of the zero-temperature quantum fluctuations of a granular film, modeled by a regular lattice of Josephsoncoupled grains, is presented. For small grains, whose junction reactance is determined by virtual quasi-particle tunneling, mean field theory predicts a universal threshold
