Most probable path and invariant sets in noise-induced transition to turbulence
Yoshiki Hiruta, Kento Yasuda, Kenta Ishimoto
Turbulence transition often arises from a subcritical transition between bistable states characterized by invariant sets of deterministic dynamical systems, and such transitions ca…

Emergence of edge state in suspension of self-propelled particles
Yoshiki Hiruta, Kenta Ishimoto
We numerically study a model convection system of a suspension of self-propelled particles, motivated by recent experimental findings of localized and bistable bioconvection patter…

Locomotion on a lubricating fluid with spatial viscosity variations
Takahiro Kanazawa, Kenta Ishimoto
We studied locomotion of a crawler on a thin Newtonian fluid film whose viscosity varied spatially. We first derived a general locomotion velocity formula with fluid viscosity vari…
