Abstract

The current-phase relation (CPR) of Josephson junctions based on high-T _c superconductors and other types of superconducting structures contain second harmonics. In this work, the influence of second harmonics of CPR on an externally shunted Josephson junction circuit model with nonzero inductance has been studied to analyze the chaotic dynamics of the system. Having constructed the circuit model, the time dependent simulations are carried out for a variety of control parameters. It is shown that the presence of second harmonics leads to a change in the boundary of the chaotic region in bifurcation diagram.
