Dynamic stabilization in the double-well Duffing oscillator
Physical Review E, 2000 Bifurcations associated with stability of the saddle fixed point of the Poincar map, arising from the unstable equilibrium point of the potential, are investigated in a forced Duffing oscillator with a double-well potential. One interesting behavior is the dynamic stabilization of the saddle fixed point.
