Noise-driven loss of chimera states and bifurcations in a nonlocal oscillator ring
Lintao Liu, Nariya Uchida
Independent phase noise can remove the spatial contrast of a chimera while leaving substantial collective coherence. We study this transition in a nonlocally coupled Kuramoto--Saka…

Defect states as a precursor of the chimera states in a ring of non-locally coupled oscillators
Tianjing Zhou, Nariya Uchida
We investigate the transition from synchronized to chimera states in a ring of non-locally coupled phase oscillators. Our focus is on the intermediate defect states, where solitary…

Topological defects in spiral wave chimera states
Lintao Liu, Nariya Uchida
Chimera states, characterized by the coexistence of coherent and incoherent domains, represent a paradigm of self-organization in complex systems. In this study, we introduce a top…
