约瑟夫森结阵列中超混沌的控制

摘要

The array composed of two resistive-capacitive-inductive-shunted (RCL-shunted) Josephson junctions (RCLSJJ) and a shunted resistor shows hyper-chaos behaviors under some parameter conditions. Here a scheme for controlling hyper-chaos in the RCLSJJ array is presented by using directionally coupled method. Numerical investiga-tions show that this scheme can be effectively used to control hyper-chaos states in this array into stable periodic states by appropriately adjusting the value of coupling intensity.%　　由两个电阻电容电感分路的约瑟夫森结和一个分路电阻组成的阵列在一些参数条件下具有超混沌行为，根据单向耦合法提出一个控制阵列中超混沌的方案。数值研究表明，通过适当调节耦合强度的大小，该方案能有效地控制这个阵列中的超混沌使之进入稳定的周期状态。
