From phase synchronization to waveform proportionality in a population of Rössler oscillators driven by an external pacemaker
Yuzuru Mitsui, Shigefumi Hata, Hiroshi Kori
The dynamical order of self-sustained oscillators is often characterized by phase synchronization, extensively studied within the framework of the Kuramoto model. It has recently b…

Degree heterogeneity shapes escape mechanisms in networks of diffusively coupled bistable elements
Hidemasa Ishii, Hiroshi Kori
For fully connected populations of diffusively coupled bistable elements, we identified three qualitatively distinct mechanisms of noise-induced escape as coupling strength varies…

Inferring Coupled Stuart-Landau Equations from Waveforms
Yuki Araya, Hiroaki Ito, Hiroshi Kori +1
We present a data-driven framework to infer phase-amplitude equations of coupled limit-cycle oscillators directly from waveform measurements. Exploiting the universality of the Stu…
