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…
Theory of phase reduction from hypergraphs to simplicial complexes: a general route to higher-order Kuramoto models
Iván León, Riccardo Muolo, Shigefumi Hata +1
Phase reduction is a powerful technique in the study of nonlinear oscillatory systems. Under certain assumptions, it allows us to describe each multidimensional oscillator by a sin…
Higher-order interactions induce anomalous transitions to synchrony
Iván León, Riccardo Muolo, Shigefumi Hata +1
We analyze the simplest model of identical coupled phase oscillators subject to two-body and three-body interactions with permutation symmetry. This model is derived from an ensemb…
Pattern formation in multiplex networks
Nikos E. Kouvaris, Shigefumi Hata, Albert Díaz-Guilera
The advances in understanding complex networks have generated increasing interest in dynamical processes occurring on them. Pattern formation in activator-inhibitor systems has bee…
Optimal phase response curves for stochastic synchronization of limit-cycle oscillators by common Poisson noise
Shigefumi Hata, Kensuke Arai, Roberto F. Galán +1
We consider optimization of phase response curves for stochastic synchronization of non-interacting limit-cycle oscillators by common Poisson impulsive signals. The optimal functio…
Synchronization of uncoupled oscillators by common gamma impulses: from phase locking to noise-induced synchronization
Shigefumi Hata, Takeaki Shimokawa, Kensuke Arai +1
Nonlinear oscillators can mutually synchronize when they are driven by common external impulses. Two important scenarios are (i) synchronization resulting from phase locking of eac…
