Generalized three-sphere microswimmers

K Yasuda, Y Hosaka, S Komura - Journal of the Physical Society of …, 2023 - journals.jps.jp
Among several models for microswimmers, the three-sphere microswimmer proposed by
Najafi and Golestanian captures the essential mechanism for the locomotion of a …

Odd elastohydrodynamics: non-reciprocal living material in a viscous fluid

K Ishimoto, C Moreau, K Yasuda - PRX Life, 2023 - APS
Motility is a fundamental feature of living matter, encompassing single cells and collective
behavior. Such living systems are characterized by nonconservativity of energy and a large …

The effects of hydrodynamic interactions on the swimming velocity and stability of a swarm of microswimmers

A Córdoba, JD Schieber - Physics of Fluids, 2023 - pubs.aip.org
The dynamics and stability of a swarm of microswimmers is examined here using a
thermodynamically compliant microswimmer model. The theory presented in this work is a …

Time-correlation functions of stochastic three-sphere micromachines

J Li, Z Zhang, Z Hou, K Yasuda, L He, S Komura - Physical Review E, 2024 - APS
We discuss and compare the statistical properties of two stochastic three-sphere
micromachines, ie, odd micromachine and thermal micromachine. We calculate the steady …

Emergence of odd elasticity in a microswimmer using deep reinforcement learning

LS Lin, K Yasuda, K Ishimoto, S Komura - Physical Review Research, 2024 - APS
We use the Deep Q-Network with reinforcement learning to investigate the emergence of
odd elasticity in an elastic microswimmer model. For an elastic microswimmer, it is …

Reciprocal microswimmers in a viscoelastic fluid

K Yasuda, M Kuroda, S Komura - Physics of Fluids, 2020 - pubs.aip.org
We suggest several reciprocal swimming mechanisms that lead to locomotion only in
viscoelastic fluids. In the first situation, we consider a three-sphere microswimmer with a …

Nonequilibrium probability flux of a thermally driven micromachine

I Sou, Y Hosaka, K Yasuda, S Komura - Physical Review E, 2019 - APS
We discuss the nonequilibrium statistical mechanics of a thermally driven micromachine
consisting of three spheres and two harmonic springs [Y. Hosaka et al., J. Phys. Soc. Jpn …

Mechanics of cell crawling by means of force-free cyclic motion

M Tarama, R Yamamoto - journal of the physical society of japan, 2018 - journals.jps.jp
The mechanics of crawling cells on a substrate is investigated by using a minimal model that
satisfies the force-free condition. A cell is described by two subcellular elements connected …

A general perturbative approach for bead-based microswimmers reveals rich self-propulsion phenomena

S Ziegler, M Hubert, N Vandewalle… - New journal of …, 2019 - iopscience.iop.org
Studies of model microswimmers have significantly contributed to the understanding of the
principles of self-propulsion we have today. However, only a small number of microswimmer …
