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…
Data-driven inference of Hopf normal form representations from oscillatory time series
Shinsuke Koyama, Ryota Kobayashi
We introduce a data-driven framework that maps noisy oscillatory time series directly onto the Hopf normal form, enabling inference of underlying dynamics without knowledge of gove…
Time-resolved synchronization analysis of stacked intrinsic Josephson junctions of a cuprate superconductor with frequency-modulated terahertz radiation spectra
Masashi Miyamoto, Keisuke Mizoguchi, Ryota Kobayashi +3
Terahertz radiation from intrinsic Josephson junctions (IJJs) provides an ideal platform to study the synchronization of a macr…
Distinguishing pairwise and higher-order interactions in coupled oscillators from time series
Weiwei Su, Shigefumi Hata, Hiroshi Kori +2
Rhythmic phenomena, which are ubiquitous in biological systems, are typically modelled as systems of coupled limit cycle oscillators. Recently, there has been an increased interest…
Manipulating Collective Opinion through Social Network Intervention
Shigefumi Hata, Renaud Lambiotte, Hiroya Nakao +1
Social media platforms have transformed the dynamics of collective opinion formation, enabling rapid, large-scale interactions while simultaneously exposing online discourse to pol…
Network inference applicable to both synchronous and desynchronous systems from oscillatory signals
Akari Matsuki, Hiroshi Kori, Ryota Kobayashi
Synchronization is ubiquitous in nature, which is mathematically described by coupled oscillators. Synchronization strongly depends on the interaction network, and the network play…
