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…
Swarming and Opinion Dynamics
Rommel Tchinda Djeudjo, Dibakar Ghosh, Timoteo Carletti
Collective dynamics in multi-agent systems provide a powerful framework for understanding how coherent group-level patterns can emerge from simple interactions between individuals.…
The role of asymmetric time delay and its structure in 1D swarmalators
Rommel Tchinda Djeudjo, Gourab Kumar Sar, Timoteo Carletti
Swarmalators are a class of coupled oscillators that simultaneously synchronize in both space and phase, providing a minimal model for systems ranging from biological microswimmers…
Classification of Chimera States via Fourier Analysis and Unsupervised Learning
Rommel Tchinda Djeudjo, Riccardo Muolo, Thierry Njougouo +1
Chimera states are among the most intriguing phenomena in nonlinear dynamics, characterized by the coexistence of coherent and incoherent behavior in systems of coupled identical o…
On rankings in multiplayer games with an application to the game of Whist
Alexis Coyette, Charles Modera, Candy Sonveaux +14
We propose a novel extension of the Bradley-Terry model to multiplayer games and adapt a recent algorithm by Newman [1] to our model. We demonstrate the use of our proposed method…
