Basin Metamorphosis in Coupled Phase Oscillators
Jin Yan, Ayumi Ozawa, Hiroshi Kori +1
We investigate the global basin structure of twisted states in nearest-neighbor coupled phase oscillators with a common phase shift . As increases, basin boundaries become…

An Isochron-Free Framework for Phase Reduction and Coupling Inference
Akari Matsuki, Ryota Kobayashi, Hiroshi Kori
Phase description provides a compact and powerful framework for analyzing synchronization dynamics in weakly coupled limit-cycle oscillators. While its classical formulation relies…

Criticality of nonreciprocal phase oscillators with long-range interactions
Minwoo Bae, Hiroshi Kori
We study noisy identical Kuramoto-Sakaguchi oscillators with phase lag , where induces nonreciprocal interactions. Numerical phase diagrams in the …
