Synchronization transitions in a hyperchaotic SQUID trimer

The phenomena of intermittent and complete synchronization between two out three identical, magnetically coupled SQUIDs (Superconducting QUantum Interference Devices) are investigated numerically. highly nonlinear superconducting oscillators/devices that exhibit strong resonant tunable response to applied magnetic field(s). Single SQUID arrays technologically important solid state devices, they also serve as a testbed for exploring numerous complex dynamical phenomena. In oligomers, the dynamic complexity increases considerably with number SQUIDs. trimer, considered here in linear geometrical configuration using realistic model accesible control parameters, exhibits chaotic hyperchaotic behavior wide parameter regions. Complete chaos well trimer is identified characterized Lyapunov spectrum system appropriate measures. passage from seems be related chaos-hyperchaos transitions has been conjectured early days synchronization.
