Phase diagram of a Josephson junction with a "periodic" dissipation
The effect of the quantum shot noise ("periodic" dissipation) on the properties of the Josephson junction is studied. At σ<1, where σ is the exponent showing the degree to which the "nonlocal"-dissipation kernel decreases, ~τ ~(1 + σ), the system is found to undergo a phase transition. The characteristics of this phase transition are found. A phase diagram, which differs from the phase diagram in the case of a Gaussian quantum noise, is constructed.
