Amplitude death, oscillation death, wave, and multistability in identical Stuart-Landau oscillators with conjugate coupling

Abstract In this work, we investigate the dynamics in a ring of identical Stuart–Landau oscillators with conjugate coupling systematically. We analyze the stability of the amplitude death and find the stability independent of the number of oscillators. When the amplitude death state is unstable, a large number of states such as homogeneous oscillation death, heterogeneous oscillation death, homogeneous oscillation, and wave propagations are found and they may coexist. We also find that all of these states are related to the unstable spatial modes to the amplitude death state.
