Subharmonic autoresonance
Adiabatic passage through higher order resonances in a perturbatively driven dynamical system with a slow control parameter, yields persisting phase locking and a strong long time response. The phenomenon has a sharp threshold on the driving amplitude, which scales with the control parameter chirp rate A and resonance order n, as A(3/(4n)).
