Synchronization of Spatiotemporal Chaos: The Regime of Coupled Spatiotemporal Intermittency

Impulsive control and synchronization of spatiotemporal chaos

The impulsive control of spatiotemporal chaos of a particular type of non-linear partial differential equations has been investigated. A criterion for the solutions of these partial differential equations to be equi-attractive in the large is determined and an estimate for the basin of attraction is given in terms of the impulse durations and the magnitude of the impulses. Extending these resul...

Stability of Wavelengths and Spatiotemporal Intermittency in Coupled Map Lattices

In relation to spatiotemporal intermittency, as it can be observed in coupled map lattices, we study the stability of different wavelengths in competition. Introducing a two dimensional map, we compare its dynamics with the one of the whole lattice. We conclude a good agreement between the two. The reduced model also allows to introduce an order parameter which combines the diffusion parameter ...

Dynamic characterizers of spatiotemporal intermittency.

We study spatiotemporal intermittency (STI) in a system of coupled sine circle maps. The phase diagram of the system shows parameter regimes where the STI lies in the directed percolation (DP) class, as well as regimes which show pure spatial intermittency (where the temporal behavior is regular) which do not belong to the DP class. Thus both DP and non-DP behavior can be seen in the same syste...

Switching of Synchronization States in Coupled Maps by Intermittency Chaos

In this study, we investigate switching synchronization phenomena which are observed in coupled chaotic maps. Two logistic maps with generating intermittency chaos near three periodic window are coupled as a CML coupling topology. Moreover, we compare obtained synchronization states of coupled maps with coupled chaotic circuits.
