Odd elasticity of a catalytic micromachine
Akira Kobayashi, Kento Yasuda, Kenta Ishimoto +4
We perform numerical simulations of a model micromachine driven by catalytic chemical reactions. Our model includes a mechano-chemical coupling between the structural variables and…
Onsager's variational principle for nonreciprocal systems with odd elasticity
Li-Shing Lin, Kento Yasuda, Kenta Ishimoto +2
Using Onsager's variational principle, we derive dynamical equations for a nonequilibrium active system with odd elasticity. The elimination of the extra variable that is coupled t…
Shapes optimising grand resistance tensor entries for a rigid body in a Stokes flow
Clment Moreau, Kenta Ishimoto, Yannick Privat
We investigate the optimal shapes of the hydrodynamic resistance of a rigid body set in motion in a Stokes flow. In this low Reynolds number regime, the hydrodynamic drag propertie…
Most probable path of an active Brownian particle
Kento Yasuda, Kenta Ishimoto
In this study, we investigate the transition path of a free active Brownian particle (ABP) on a two-dimensional plane between two given states. The extremum conditions for the most…
A hydrodynamic slender-body theory for local rotation at zero Reynolds number
Benjamin J. Walker, Kenta Ishimoto, Eamonn A. Gaffney
Slender objects are commonplace in microscale flow problems, from soft deformable sensors to biological filaments such as flagella and cilia. Whilst much research has focussed on t…
Emergent rheotaxis of shape-changing swimmers in Poiseuille flow
Benjamin J. Walker, Kenta Ishimoto, Clément Moreau +2
A simple model for the motion of shape-changing swimmers in Poiseuille flow was recently proposed and numerically explored by Omori et al. (2022). These explorations hinted that a…
Time-correlation functions for odd Langevin systems
Kento Yasuda, Kenta Ishimoto, Akira Kobayashi +4
We investigate the statistical properties of fluctuations in active systems that are governed by non-symmetric responses. Both an underdamped Langevin system with an odd resistance…
