Networks of Josephson junctions and their synchronization
Abstract
One can demonstrate that a 1D Josephson network containing junctions with different tunneling resistances can be synchronized at frequencies, which are multiples of 2eV, where V is the total dc voltage applied across the network. The appearance of such synchronization follows from the law of charge conservation and takes place if charge transfer is dominated by the Josephson channel. One can observe also a subharmonic structure. The result holds for clusterbased arrays as well as for the general case of a tunneling network.
