Phase-coupled oscillators serve as paradigmatic models of networks of weakly interacting oscillatory units in physics and biology. The order parameter which quantifies synchronization so far has been found to be chaotic only in systems with inhomogeneities. Here we show that even symmetric systems of identical oscillators may not only exhibit chaotic dynamics, but also chaotically fluctuating order parameters. Our findings imply that neither inhomogeneities nor amplitude variations are…

Chaos in generically coupled phase oscillator networks with nonpairwise interactions.

It is shown that chaos can appear in the smallest possible dimension of four coupled phase oscillators for a range of parameter values and can give rise to complex emergent dynamics in symmetric phase oscillator networks.

Disorder-induced dynamics in a pair of coupled heterogeneous phase oscillator networks.

Most of the interesting dynamics of a pair of coupled heterogeneous phase oscillator networks can be understood by analysing a gluing bifurcation of periodic orbits; these orbits can be thought of as "breathing chimeras" in the limit of identical oscillators.

Chaos in small networks of theta neurons.

The robustness of the chaotic behaviour with respect to changes in initial conditions and parameters is investigated and it is found to be quite robust as long as the reversibility of the system is preserved.

Irregular collective dynamics in a Kuramoto–Daido system

We analyze the collective behavior of a mean-field model of phase-oscillators of Kuramoto–Daido type coupled through pairwise interactions which depend on phase differences: the coupling function is

Chaotic weak chimeras and their persistence in coupled populations of phase oscillators

Nontrivial collective behavior may emerge from the interactive dynamics of many oscillatory units. Chimera states are chaotic patterns of spatially localized coherent and incoherent oscillations. The

Systems of N identical globally coupled phase oscillators can demonstrate a multitude of complex behaviors. Such systems can have chaotic dynamics for N > 4 when a coupling function is biharmonic.

Even fully deterministic dynamics may be chaotic, i.e., essentially unpredictable as time evolves. The first part of this thesis concerns the emergence of chaos in dynamical systems with symmetry,

We argue that a discrete Shilnikov attractor exists in the system of five identical globally coupled phase oscillators with biharmonic coupling. We explain the scenario that leads to birth of this

This paper shows that navigation may be done reliably even in the presence of noise and frequency detuning, as long as the input amplitude dominates the noise strength and the detuning magnitude, and the time between the applied pulses is in a suitable range.
