Van Hemmen interactions in a one-dimensional swarmalator model
Kevin O'Keeffe
We study a one-dimensional swarmalator model with van Hemmen pair disorder in the phase coupling. Pair disorder has two effects. First, it splits the static ring-model states into…
Self-propulsion in the 1D swarmalator model
Kevin P. O'Keeffe
We study the 1D swarmalator model augmented with self-propulsion. Each swarmalator swims along the ring at a speed fixed by its orientation . Self-propulsion unfo…
Coupling-split clusters in a swarmalator model with uniform coupling disorder
K. P. O'Keeffe
We study the one-dimensional swarmalator model in which the phase coupling is drawn from a uniform distribution. Our main result is a static coupling-split cluster, in which…
Time delay in the 1d swarmalator model
K. P. O'Keeffe, Jason Hindes
We study the 1d swarmalator model augmented with time delayed coupling. Along with the familiar sync, async, and phase wave states, we find a family of unsteady states where the or…
Topological transitions in swarmalators systems
Patrick Louodop, Michael N. Jipdi, Gael R. Simo +6
After its development, the swarmalators model attracted a great deal of attention since it was found to be very suitable to reproduce several behaviors in collective dynamics. Howe…
Interplay of sync and swarm: Theory and application of swarmalators
Gourab Kumar Sar, Kevin O'Keeffe, Joao U. F. Lizarraga +3
Swarmalators, entities that combine the properties of swarming particles with synchronized oscillations, represent a novel and growing area of research in the study of collective b…
Dynamics of pulsating swarmalators on a ring
Samali Ghosh, Kevin O'Keeffe, Gourab Kumar Sar +1
We study a simple one-dimensional model of swarmalators, a generalization of phase oscillators that swarm around in space as well as synchronize internal oscillations in time. Prev…
On forced swarmalators that move in higher-dimensional spaces
Md Sayeed Anwar, Dibakar Ghosh, Kevin O'Keeffe
We study the collective dynamics of swarmalators subjected to periodic (sinusoidal) forcing. Although previous research focused on the simplified case of motion in a one-dimensiona…
Effects of coupling range on the dynamics of swarmalators
Gourab Kumar Sar, Kevin O'Keeffe, Dibakar Ghosh
We study a variant of the one-dimensional swarmalator model where the units' interactions have a controllable length scale or range. We tune the model from the long-range regime, w…
Global synchronization theorem for coupled swarmalators
Kevin P. O'Keeffe
The global stability of oscillator networks has attracted much recent attention. Ordinarily, the oscillators in such studies are motionless; their spatial degrees of freedom are ei…
Stability of the 1d swarmalator model in the continuum limit
Kevin O'Keeffe
We study the 1d swarmalator model in the continuum limit. We examine the stability of its collective states which have compact support: synchrony, where the swarmalators lie in two…
The forced one-dimensional swarmalator model
Md Sayeed Anwar, Dibakar Ghosh, Kevin O'Keeffe
We study a simple model of swarmalators subject to periodic forcing and confined to move around a one-dimensional ring. This is a toy model for physical systems with a mix of sync,…
Order, chaos, and dimensionality transition in a system of swarmalators
Joao U. F. Lizarraga, Kevin P. O'Keeffe, Marcus A. M. de Aguiar
Similar to sperm, where individuals self-organize in space while also striving for coherence in their tail swinging, several natural and engineered systems exhibit the emergence of…
A solvable two-dimensional swarmalator model
Kevin O'Keeffe, Gourab Kumar Sar, Md Sayeed Anwar +3
Swarmalators are oscillators that swarm through space as they synchronize in time. Introduced a few years ago to model many systems which mix synchrony with self-assembly, they rem…
Swarmalators on a ring with uncorrelated pinning
Gourab Kumar Sar, Kevin O'Keeffe, Dibakar Ghosh
We present a case study of swarmalators (mobile oscillators) which move on a 1D ring and are subject to pinning. Previous work considered the special case where the pinning in spac…
Attractive and repulsive interactions in the one-dimensional swarmalator model
Baoli Hao, Ming Zhong, Kevin O'Keeffe
We study a population of swarmalators, mobile variants of phase oscillators, which run on a ring and have both attractive and repulsive interactions. This one-dimensional (1D) swar…
Sync and swarm: solvable model of non-identical swarmalators
S. Yoon, K. P. O'Keeffe, J. F. F. Mendes +1
We study a model of non-identical swarmalators, generalizations of phase oscillators that both sync in time and swarm in space. The model produces four collective states: asynchron…
