Extreme events in SQUID trimer

Abstract

The formation of distinct intermittent large-amplitude dynamics has been investigated in three magnetically coupled Superconducting QUantum Interference Devices (SQUIDs). The proposed model manifests abrupt large-amplitude events from a bounded region at sporadic time intervals. The unforeseen deviation occurs from either regular or chaotic motion via different dynamical processes of interior crisis-induced intermittency, Pomeau–Manneville intermittency, and quasiperiodic intermittency. The advent of extremely large-amplitude dynamics and their transition are evaluated, using appropriate dynamical and statistical analyses. Our observation enlightened the possibility of utilizing the SQUIDs more efficiently and harmlessly in distinct applications while taking note of the emergence of atypical behavior in the system.
