摘要：

We studied the phase-locking behavior of Josephson junctions in two-dimensional arrays under microwave irradiation or coupled to a resonant cavity. We are able to identify the phase-locked junctions by means of spatially resolving measurements. We focus on the degree of coherence in the arrays, changing from incoherent to coherent oscillations of the junctions when the microwave power is increased. We interpret our results in terms of a second order phase transition to the phase-locked state.
