The authors investigate the dynamics and the phase diagram of Josephson junctions where the dissipation is due to quasiparticle tunneling. This system is formally equivalent to a one-dimensional X-Y model with easy axis and long-range interaction. It has a phase transition at a critical strength of the dissipation, which differs in several respects from the one encountered if the dissipation is Ohmic. Quantum effects are reduced, though not destroyed, above this transition. The authors discuss the response of a junction to an imposed current. In the linear regime Coulomb blockade is important; in the nonlinear regime under suitable conditions Bloch oscillations can occur.
