Abstract
We suggest that the reported noise-rise phenomenon observed in Josephson oscillators can be understood in terms of the full nonlinear and deterministic junction dynamics. We show that the drive damped pendulum equation describing the junction behavior exhibits chaotic solutions associated with the appearance of strange attractors in phase space. These results are relevant to the general problem of turbulent behavior of anharmonic systems.
