Information geometry and synchronization phase transition in the Kuramoto model

Phys Rev E. 2023 Apr;107(4-1):044211. doi: 10.1103/PhysRevE.107.044211.

Abstract

We discuss how the synchronization in the Kuramoto model can be treated in terms of information geometry. We argue that the Fisher information is sensitive to synchronization transition; specifically, components of the Fisher metric diverge at the critical point. Our approach is based on the recently proposed relation between the Kuramoto model and geodesics in hyperbolic space.
