Near-field Hydrodynamics Disentangles Angular Correlations in Confined Active Suspensions
Changle Liao, Haruki Hayano, Yuto Uesugi +3
Spatial confinement profoundly impacts the transport and self-organization of active matter across diverse biological systems. While the collective orders in confined active matter…
Various phases of active matter emerging from bacteria and their implications
Kazumasa A. Takeuchi, Daiki Nishiguchi
In this perspective article, we discuss bacterial populations as a model system of active matter. It allows for the exploration and characterization of various phases of active mat…
Designing topological edge states in bacterial active matter
Yoshihito Uchida, Daiki Nishiguchi, Kazumasa A. Takeuchi
Topology provides a unifying framework for understanding robust transport through protected edge states arising from nontrivial wavenumber topology. Extending these concepts to act…
Learning general pair interactions between self-propelled particles
Jérôme Hem, Alexis Poncet, Pierre Ronceray +2
Synthetic active matter systems, such as active colloids, often have complex interactions, which can be of hydrodynamic, chemical or electrostatic origin and cannot be computed fro…
Vortex reversal is a precursor of confined bacterial turbulence
Daiki Nishiguchi, Sora Shiratani, Kazumasa A. Takeuchi +1
Active turbulence, or chaotic self-organized collective motion, is often observed in concentrated suspensions of motile bacteria and other systems of self-propelled interacting age…
Quasi-two-dimensional bacterial swimming around pillars: enhanced trapping efficiency and curvature dependence
Yuki Takaha, Daiki Nishiguchi
Microswimmers exhibit more diverse behavior in quasi-two dimensions than in three dimensions. Such behavior remains elusive due to the analytical difficulty of dealing with two par…
Flagellar Dynamics of Chains of Active Janus Particles Fueled by an AC electric field
Daiki Nishiguchi, Junichiro Iwasawa, Hong-Ren Jiang +1
We study the active dynamics of self-propelled asymmetrical colloidal particles (Janus particles) fueled by an AC electric field. Both the speed and the direction of the self-propu…
Mesoscopic Turbulence and Local Order in Janus Particles Self-Propelling under an AC Electric Field
Daiki Nishiguchi, Masaki Sano
To elucidate mechanisms of mesoscopic turbulence exhibited by active particles, we experimentally study turbulent states of non-living self-propelled particles. We realize an exper…
