Abstract
We investigate the dynamics of a soliton that behaves as an extended p article. The soliton motion in an effective bistable potential can be chaotic in a similar way as the Duffing oscillator. We generalize the concept of geometrical resonance to spatiotemporal systems and apply i t to design a nonfeedback mechanism of chaos control using localized p erturbations. We show the existence of solitonic stochastic resonance.
