Manipulating synchronous states by dynamical flow in complex networks

Accepted: 3 August 2007
We show that if the dynamical flow, i.e., the non-vanishing coupling term, exists between nodes in synchronized networks, a wide variety of stable synchronous states of complex networks may occur, which may differ substantially from the dynamics of an individual isolated node. Stability analysis of the dynamics of Hindmarsh-Rose and foodweb networks shows that controlling this dynamical flow can greatly enhance the synchronization and generate both chaotic and regular synchronous states for whatever state of an isolated node. Our results provide a possibility for the control of synchronization in complex networks by the manipulation of the dynamical flow.
