State-dependent communication enhances network synchronization

February 26 @ 4:00 pm - 5:30 pm

State-Dependent Communication Enhances Network Synchronization Synchronization occurs in many natural and artificial systems, which are often described as networks. Although synchronization requires communication between the individual systems or oscillators that form the network, the communication strategies that are responsible for synchronization are not always well understood. Most models of network synchronization assume that the connected individual systems are either permanently or intermittently communicating with one another. However, in most biological systems communication occurs when the individual oscillators reach a particular state, for example neurons in the brain transmit signals to the other neurons after they “fire”. We investigate analytically, numerically, and experimentally network synchronization strategies that depend on the “transverse reactivity” of a synchronous oscillation, i.e., the instantaneous rate of growth of a perturbation about an oscillation. We show great advantage of such strategies both in terms of coupling expenditure and energy efficiency and propose that similar strategies could be conveniently used in technological applications.
