Summary

Regime in which a system easefully and continuously traverses a sequence of states without falling into a given stable attractor Tognoli2014

A metastable system is one in which states are locally stable yet vulnerable to perturbations, resulting in frequent transitions between states.

A metastable system that fluctuates between states of synchronization and desynchronization is poised at criticality.

Typically modeled with the Kuramoto order parameter

Variability across time of the global level of synchronisation of a system Escrichs2022.

• Also known as the global Kuramoto order parameter of a dynamical system.

Closely linked to the entropy of the dynamics of a system Girn2023
