Coherent spatial structure versus time chaos in a perturbed sine-Gordon system
Journal Article

· Phys. Rev. Lett.; (United States)
A novel interplay of coherent spatial structure and temporal chaos is reported for the ac-driven, damped sine-Gordon system with breather initial conditions and periodic boundary conditions. The competing tendencies of spatial structures to be stable and of single-particle motions to be chaotic can lead to suppression of chaos, spatio-temporal intermittency, and symmetry-breaking tendencies. Dynamic structure factors provide direct evidence for spatial period halving and renormalized-phonon generation in chaotic regimes.
