Beyond 11/16: dense Kuramoto networks that resist synchrony
Kevin P. O'Keeffe
How densely must a network of identical Kuramoto oscillators be wired before synchrony is its only stable state? The answer is a critical connectivity (the minimum degree div…
Delay-induced multistability in one-dimensional swarmalators with common intrinsic frequency
Rommel Tchinda Djeudjo, Timoteo Carletti, Kevin P. O'Keeffe
We study the delayed one-dimensional swarmalator model when all units share a common intrinsic frequency ω. Unlike the zero-frequency case, ω cannot be removed by a rotating-frame…
Rare but stable: hidden states in the 1D swarmalator model
Rommel Tchinda Djeudjo, Kevin P. O'Keeffe, Timoteo Carletti
The one-dimensional swarmalator model is usually understood through three macroscopic states: synchrony, the phase wave, and asynchrony. We show that the identical model also conta…
Arithmetic of the sync basin for pulse-coupled oscillators
K. P. O'Keeffe
A population of identical pulse-coupled oscillators ultimately settles into one of two outcomes: full synchrony or a state of co-existing synchronized clusters. We show that wh…
Learning to Synchronize in Minimum Time
Kevin. P. O'Keeffe
The minimum-time feedback law for driving a population of coupled oscillators into synchrony is unknown. Here we settle it for identical Kuramoto oscillators under an instantaneous…
Synchrony by Birth and Death
K. P. O'Keeffe
A population of oscillators typically synchronizes because coupling pulls their phases together. Here we consider malthusian oscillators whose coupling is demographic: oscillators…
