摘要
通过计算机模拟研究了电阻电容分路的约瑟夫森结中的混沌行为,给出了结电压随阻尼参数及偏置直流电流变化的分岔图,从而展示了混沌产生的方式及混沌出现的参数区间,并基于弱周期扰动理论提出了控制RCSJJ中混沌的方案,模拟结果证明了该方案的有效性.
This paper studies chaotic behavior in RC-shunted Josephson junction (RCSJJ) by computer simulations. We present the bifurcation diagram of junction voltage via damping parameter or dc bias current, and show the routes of chaos generation and parameter ranges where chaos occurs. On the other hand, a scheme for chaos control in RCSJJ is proposed based on weak periodic perturbations theory, the simulation results demonstrate the validity of this scheme.
