Synchronization of chaos in RCL-shunted Josephson junctions array

We present a scheme for chaotic synchronization in two resistive-capacitive-inductance shunted Josephson junction (RCLSJJ) arrays by using another chaotic RCLSJJ array as the drive system. Numerical simulations show that whether the two RCLSJJ arrays are chaotic or not before being driven, they can realize chaotic synchronization with a suitable driving intensity, under which the maximum condition Lyapunov exponent (MCLE) is negative.
