The dynamics of ensembles of phase oscillators are usually described considering their infinite-size limit. In practice, however, this limit is fully accessible only if the Ott-Antonsen theory can be applied, and the heterogeneity is distributed following a rational function. In this work, we demonstrate the usefulness of a moment-based scheme to reproduce the dynamics of infinitely many oscillators. Our analysis is particularized for Gaussian heterogeneities, leading to a Fourier-Hermite…

Enlarged Kuramoto model: Secondary instability and transition to collective chaos.
The emergence of collective synchrony from an incoherent state is a phenomenon essentially described by the Kuramoto model. This canonical model was derived perturbatively, by applying phase
Dynamics in the Sakaguchi-Kuramoto model with bimodal frequency distribution
TLDR
This work reduces the globally coupled phase oscillators to low dimensional coupled ordinary differential equations by using Ott-Antonsen ansatz and analyzes the stabilities of the incoherent state and different partial synchronous states in the Sakaguchi-Kuramoto model.

TLDR
An isochron-based scheme is developed to obtain the second-order phase approximation, which reproduces the weak-coupling dynamics of the MF-CGLE at moderate coupling.

Abrupt Desynchronization and Extensive Multistability in Globally Coupled Oscillator Simplexes.
TLDR
This analysis of the collective dynamics of a large ensembles of dynamical units with nonpairwise interactions, namely coupled phase oscillators with three-way interactions, sheds light on the complexity that can arise in physical systems with simplicial interactions like the human brain and the role that simplified interactions play in storing information.
