(180) If the system is driven out of equilibrium, the instantaneous distribution function is timedependent. Eq. (180) states that the non-equilibrium distribution tries to follow the instantaneous distribution but can do that at best with a time lag determined by . The time-dependent readjustment of the distribution is achieved with inelastic processes and is thus dissipative. To "nd the resulting noise we investigate the response of the current to a small oscillating phase ()e superimposed on the dc phase. The current is I"!(e/)[(d /d) #(d /d) ]. The Josephson relation, d/dt"!(2e/)
