COMPLEX DYNAMICAL BEHAVIOR IN RCL-SHUNTED JOSEPHSON-JUNCTIONS

We present numerical simulation results on the dynamical behavior of r esistively, capacitively and inductively shunted Josephson tunnel junc tions (RCLSJ). We found Josephson oscillations, chaotic oscillations, subharmonic oscillations and relaxation oscillations dominate the dyna mics of the circuit in this order as we increase the inductance of the shunt. Long apparently chaotic transient states were found in the int ermediate range values of the shunt inductance. Difficulties in compar ing simulation with experiments due to the existence of the long trans ients are discussed.
