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…
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…
