New preprint! arxiv.org/abs/2601.08243 We realized topological transport in bacterial active matter, via microfabricated geometric structures. Besides edge localization and transport of bacteria, we also captured its topological origin thru modeling. Congrats Yoshi!

2 new preprints! The 1st one arxiv.org/abs/2407.05031 is about the finding that starving bacteria form bundles akin to smectic liquid crystal. We quantified the smectic order by ML-based image analysis and discussed the relevance of extracellular substances & growth arrest.

A new preprint, "Squish jamming" arxiv.org/abs/2404.09773 We realized a model experiment of extremely deformable grains and found a novel fluid-solid transition. In contrast to usual jamming controlled by the number of contacts, our jamming is triggered by the "extent of contact".

New preprint! arxiv.org/abs/2304.03306 We unveiled the route to active turbulence under circular confinement, through a subcritical Hopf bifurcation and reentrant transitions between oscillatory and chaotic states. GPU-based scheme resolved their details. Great work by Sora!

Paper published in Commun Phys! Daiki and coauthors clarified a mechanism of boundary-induced vortex order formation in bacterial turbulence, proposing a novel boundary condition for active hydrodynamics. Beautiful combination of theory, numerics & expt's! nature.com/articles/s42005-0…
