Transition from Amplitude Death to Oscillation Death in Coupled Chua Circuits

Abstract: In this piece of work, an important transition from amplitude death (AD) to oscillation death (OD) state in coupled Chua circuit has been explored for the first time. Here, mean field diffusively (MFD) coupled Chua circuits are when additionally coupled through direct coupling, it exhibits the AD-OD transition phenomena. The effect of design parameters and coupling parameters are investigated in details. For both identical and non-identical systems the AD make transition to OD through symmetry breaking. These are investigated through numerical simulations and are established through hardware experiment. The present study includes a new dimension to versatility of Chua circuit in the field of nonlinear dynamics.
