Abstract

Self-induced current steps, period doubling bifurcations, and chaos have been observed in numerical simulations of resonator coupled Josephson junctions. The Resistively Shunted Junction (RSJ) model loaded by the admittance of simple resonant circuits is used to model a small Josephson junction integrated in the middle of an open-ended thin-film superconducting stripline resonator. Over a wide range of the effective coupling parameter most of the features seen in experiments with this system can be reproduced.
