ẋ = y(z−1+x²)+γx, ẏ = x(3z+1−x²)+γy, ż = −2z(α+xy). A strange attractor from modelling plasma wave interactions, with rich bifurcation structure.
Rabinovich–Fabrikant equations (1979) describe modulation instability in non-equilibrium media. For α=0.14, γ=0.10 the system exhibits a 4-wing strange attractor. Adjust α to see bifurcations between fixed points, limit cycles, and chaos.
