Coupled Stuart–Landau oscillators: oscillation death and revival
Oscillator death (amplitude death) occurs when coupling drives limit-cycle oscillators to a stable fixed point. In the Stuart–Landau model ż = (1 + iω - |z|²)z + K/(N)·Σzⱼ, sufficiently strong coupling between oscillators with different frequencies causes all amplitudes to collapse to zero — a counterintuitive quenching effect. Revival of oscillations (IHSS) occurs in conjugate coupling schemes.
