Directional Symmetry Breaking of Spherical Active Colloids by Magnetoviscous Coupling
Ziyang Zhou, Takuya Kobayashi, Keita Saito +5
Harnessing active matter calls for strategies that break the directional symmetry of self-propelled motion without altering the propulsion mechanism itself. Here, we show that magn…
Boundary-shape driven transitions in vortex and oscillatory dynamics of confined epithelial cells
Ryo Ienaga, Kazuyuki Shigeta, Tatsuya Fukuyama +2
Controlling the collective motion of epithelial cell populations is fundamental for understanding multicellular self-organization and for advancing tissue engineering. Under spatia…
Geometric frustration and pairing order transition in confined bacterial vortices
Kazusa Beppu, Kaito Matsuura, Yusuke T. Maeda
Dense systems of active matter exhibit highly dynamic collective motion characterized by intermingled vortices, referred to as active turbulence. The interaction between these vort…
Magnetic control of orientational order and intrinsic hydrodynamic instability in bacterial turbulence
Kazusa Beppu, Jaakko V. I. Timonen
Highly concentrated active agents tend to exhibit turbulent flows, reminiscent of classical hydrodynamic turbulence, which has attracted considerable attention lately. Controlling…
Controlling topological defects and contractile flow in confined nematic cell population
Ryo Ienaga, Kazusa Beppu, Yusuke T. Maeda
Topological defects in nematically aligned cell populations play a critical role in modulating collective motion, from microbial colonies to epithelial tissues. Despite the potenti…
Geometry-Induced Dynamics of Confined Chiral Active Matter
Archit Negi, Kazusa Beppu, Yusuke T. Maeda
Controlling the motion of active matter is a central issue that has recently garnered significant attention in fields ranging from non-equilibrium physics to chemical engineering a…
