Wave patterns in two-dimensional networks of non-locally coupled oscillators with phase delay
Phillip Nimphius, Nariya Uchida
The paper investigates how wave patterns emerge and evolve in a two‑dimensional lattice of non‑locally, repulsively coupled oscillators whose interaction is controlled by a phase d…
Dynamical Theory of Elastic Synchronization of Cardiomyocytes
Akinari Tomiie, Nariya Uchida
We study synchronization of two cardiomyocytes mediated by elastic interactions through the substrate. Modeling each cell as an oscillating force dipole governed by a Rayleigh-type…
Defect binding-unbinding transition in active nematic membranes
Yuki Hirota, Nariya Uchida
We investigate the dynamics of active nematic liquid crystals on deformable membranes, focusing on the interplay between active stress and anisotropic curvature coupling. Using a m…
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…
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…
Collective behaviors of self-propelled particles with tunable alignment angles
Zichen Qin, Nariya Uchida
We present a novel aligning active matter model by extending the nematic alignment rule in self-propelled rods to tunable alignment angles, as represented by collision of cone-shap…
