On-Off Intermittency in Randomly Driven Parallel Pumping

On-off Intermittency in Stochastically Driven Electrohydrodynamic Convection in Nematics

Perturbed on-off intermittency.

A basic requirement for on-off intermittency to occur is that the system possesses an invariant subspace. We address how on-off intermittency manifests itself when a perturbation destroys the invariant subspace. In particular, we distinguish between situations where the threshold for measuring the on-off intermittency in numerical or physical experiments is much larger than or is comparable to ...

On-off Intermittency in Electrohydrodynamic Convection in Nematics Driven by Multiplicative Noise

We report on-off intermittency in electroconvection of nematic liquid crystals driven by a dichotomous stochastic electric voltage. Above DC threshold with increasing voltage amplitude we observe laminar phases of undistorted director state interrupted by shorter bursts of regular stripes. Near a critical value of the amplitude the distribution of the duration of laminar phases is governed over...

Bubbling and on-off intermittency in bailout embeddings.

We establish and investigate the conceptual connection between the dynamics of the bailout embedding of a Hamiltonian system and the dynamical regimes associated with the occurrence of bubbling and blowout bifurcations. The roles of the invariant manifold and the dynamics restricted to it, required in bubbling and blowout bifurcating systems, are played in the bailout embedding by the embedded ...

Desynchronization and on-off intermittency in complex networks

Most existing works on synchronization in complex networks concern the synchronizability and its dependence on network topology. While there has also been work on desynchronization wave patterns in networks that are regular or nearly regular, little is known about the dynamics of synchronous patterns in complex networks. We find that, when a complex network becomes desynchronized, a giant clust...
