摘要：

We report the presence of a Farey staircase in the simulated current-voltage characteristics between the second and third harmonic steps of an underdamped Josephson junction under external electromagnetic radiation. The steps constituting the staircase are interrupted by chaotic intervals. The dynamics is due to a two-extremum return map and is not associated with phase locking on an invariant torus. On decreasing the current, the third harmonic step ends in the bifurcation known as blue-sky catastrophe.
