Chaotic Behavior in an Array of Coupled Josephson Weak Links

Using the resistively shunted junction model, an array of three resistively coupled, noncapacitive, Josephson weak links, driven only by dc bias currents, is studied for the existence of chaos. This system represents one of the set of three simplest Josephson systems that, in principle, can have chaotic dynamics. The results attest to the validity of the Ruelle-Takens-Newhouse scenario for the onset of chaos
