Spatial coherence and temporal chaos in macroscopic systems with asymmetrical couplings.

摘要: Coupled map lattices with asymmetric short-range couplings are studied analytically and numerically. If is shown that open boundary conditions these systems exhibit spatially uniform, but temporally chaotic states stable even in the thermodynamic limit. The stability of this state associated appearance a gap at zero wave number spectrum linear operator describing fluctuations about uniform state. long-range order unstable to noise. We calculate finite coherence length presence weak noise
