Universal Spatio-Temporal Chaos in Large Assemblies of Simple Dynamical Units

Large assemblies of nonlinear dynamical units driven by a stochastic field with smooth spatial variation generate strong turbulence with various scaling properties. The driving field may actually be a self-generated internal field due to long-range mutual coupling. Besides being persistent over a finite parameter range, this type of turbulence is highly independent of what kind of dynamical units are involved, and whether or not each unit is coupled with its neighborhood. Underneath the amplitude field of our direct observation, a strongly intermittent field with a multifractal structure is discovered which is reminiscent of the energy dissipation field in the fully-developed hydrodynamic turbulence.
