    "abstract": "We demonstrate that the well known phase-locking mechanism leading to Shapiro\nsteps in ac-driven Josephson junctions is always accompanied by a higher order\nphase-locking mechanism similar to that of the parametrically driven pendulum.\nThis effect, resulting in a $\\pi$-periodic effective potential for the phase,\nmanifests itself clearly in the parameter regions where the usual Shapiro steps\nare expected to vanish.",
