The mathematics behind chimera states

OE Omel'chenko - Nonlinearity, 2018 - iopscience.iop.org
Chimera states are self-organized spatiotemporal patterns of coexisting coherence and
incoherence. We give an overview of the main mathematical methods used in studies of …

Chaos in Kuramoto oscillator networks

C Bick, MJ Panaggio, EA Martens - Chaos: An Interdisciplinary Journal …, 2018 - pubs.aip.org
Kuramoto oscillators are widely used to explain collective phenomena in networks of
coupled oscillatory units. We show that simple networks of two populations with a generic …

Chimera states in two populations with heterogeneous phase-lag

EA Martens, C Bick, MJ Panaggio - Chaos: An Interdisciplinary Journal …, 2016 - pubs.aip.org
The simplest network of coupled phase-oscillators exhibiting chimera states is given by two
populations with disparate intra-and inter-population coupling strengths. We explore the …

Noise-induced macroscopic oscillations in a network of synaptically coupled quadratic integrate-and-fire neurons

I Ratas, K Pyragas - Physical Review E, 2019 - APS
We consider the effect of small independent local noise on a network of quadratic integrate-
and-fire neurons, globally coupled via synaptic pulses of finite width. The Fokker-Planck …

Macroscopic self-oscillations and aging transition in a network of synaptically coupled quadratic integrate-and-fire neurons

I Ratas, K Pyragas - Physical Review E, 2016 - APS
We analyze the dynamics of a large network of coupled quadratic integrate-and-fire
neurons, which represent the canonical model for class I neurons near the spiking threshold …

Chimeras on a ring of oscillator populations

CR Laing - Chaos: An Interdisciplinary Journal of Nonlinear …, 2023 - pubs.aip.org
Chimeras occur in networks of coupled oscillators and are characterized by coexisting
groups of synchronous oscillators and asynchronous oscillators. We consider a network …

Simple and complex chimera states in a nonlinearly coupled oscillatory medium

M Bolotov, L Smirnov, G Osipov… - … Interdisciplinary Journal of …, 2018 - pubs.aip.org
We consider chimera states in a one-dimensional medium of nonlinear nonlocally coupled
phase oscillators. In terms of a local coarse-grained complex order parameter, the problem …

Macroscopic oscillations of a quadratic integrate-and-fire neuron network with global distributed-delay coupling

I Ratas, K Pyragas - Physical Review E, 2018 - APS
We consider a large network of globally coupled quadratic integrate-and-fire neurons, which
are canonical representatives for class I neurons near the spiking threshold. The model …

Synchronization of non-weakly coupled aeroelastic oscillators

D Shenhav Feigin, O Shoshani - Communications Physics, 2024 - nature.com
Synchronized oscillators are ubiquitous in nature and engineering. Despite several models
that have been proposed to treat synchronized oscillators beyond weak coupling, the widely …

Two scenarios for the onset and suppression of collective oscillations in heterogeneous populations of active rotators

V Klinshov, I Franović - Physical Review E, 2019 - APS
We consider the macroscopic regimes and the scenarios for the onset and the suppression
of collective oscillations in a heterogeneous population of active rotators composed of …
