Ragged Synchronizability and Clustering in a Network of Coupled Oscillators
نویسندگان
چکیده
We show the phenomenon of complete synchronization in an network of coupled oscillators. We confirm that non-diagonal coupling can lead to the appearance or disappearance of synchronous windows (ragged synchronizability phenomenon) in the coupling parameter space. We also show the appearance of clusters (synchronization in one or more group) between coupled systems. Our numerical studies are confirmed by an electronic experiment.

Structural Effects on Synchronizability of Scale-free Networks
In this paper, we numerically investigate the structural characteristics that affect the synchronizability of coupled identical oscillators on scale-free networks. By using the edge-exchange method, we can change the network structure with degree sequence fixed. An optimal algorithm, namely Tabu Search, is applied, respectively, to enhance and weaken the synchronizability. The numerical results...
متن کاملAchieving synchronization of networks by an auxiliary hub
In this letter, we study complete synchronization in quite generic networks of coupled oscillators, where both the connectivity topology and coupling mechanism may be arbitrary. We propose a method, i.e., introducing an auxiliary hub which decreases the average path length and meanwhile increases the clustering coefficient of the network, to achieve complete synchronization. We demonstrate that...
متن کاملEnhancing complex-network synchronization
– Heterogeneity in the degree (connectivity) distribution has been shown to suppress synchronization in networks of symmetrically coupled oscillators with uniform coupling strength (unweighted coupling). Here we uncover a condition for enhanced synchronization in weighted networks with asymmetric coupling. We show that, in the optimum regime, synchronizability is solely determined by the averag...
متن کاملSynchronizability and Synchronization Dynamics of Weighed and Unweighed Scale Free Networks with Degree Mixing
We study the synchronizability and the synchronization dynamics of networks of nonlinear oscillators. We investigate how the synchronization of the network is influenced by some of its topological features such as variations of the power law exponent γ and the degree correlation coefficient r. Using an appropriate construction algorithm based on clustering the network vertices in p classes acco...
متن کاملEnhanced synchronizability by structural perturbations.
In this Brief Report, we investigate the collective synchronization of a system of coupled oscillators on a Barabási-Albert scale-free network. We propose an approach of structural perturbations aiming at those nodes with maximal betweenness. This method can markedly enhance the network synchronizability, and is easy to realize. The simulation results show that the eigenratio will sharply decre...
