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…
Wave patterns in two-dimensional networks of non-locally coupled oscillators with phase delay
Phillip Nimphius, Nariya Uchida
We studied the wave patterns in non-locally, repulsively coupled oscillators on a 2D lattice. The repulsive coupling is tuned by the phase delay and the wave patterns are foun…
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…
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…
Boltzmann-Ginzburg-Landau theory for autochemotaxis of active rod-like particles
Shun Sakurai, Nariya Uchida
We investigate the interplay between chemotaxis and alignment interactions in active rod-like particles, such as E. coli and Janus rods. Starting from a discrete model of self-prop…
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…
Collective excitations in active solids featuring alignment interactions
Yutaka Kinoshita, Nariya Uchida, Andreas M. Menzel
With increasing emphasis on the study of active solids, the features of these classes of nonequilibrium systems and materials beyond their mere existence shift into focus. One conc…
Active nematic liquid crystals under a quenched random field
Yutaka Kinoshita, Nariya Uchida
Coupling between flow and orientation is a central issue in understanding the collective dynamics of active biofilaments and cells. Active stresses generated by motor activity dest…
