Phase-symmetry breaking as a mechanism for subcritical transition in shell models of turbulence
Yoshiki Hiruta
Subcritical transition to turbulence, in which the laminar state is linearly stable yet finite-amplitude perturbations develop into turbulence, is ubiquitous but lacks a simple ana…

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…
