Hydrodynamic Choreographies of Microswimmers [PDF]
Scientific Reports, 2018 AbstractWe unveil orbital topologies of two nearby swimming microorganisms using an artificial microswimmer, called Quadroar. Depending on the initial conditions of the microswimmers, we find diverse families of attractors including dynamical equilibria, bound orbits, braids, and pursuit–evasion games. We also observe a hydrodynamic slingshot effect: a

Learning to cooperate for low-Reynolds-number swimming: a model problem for gait coordination
Scientific Reports, 2023 Biological microswimmers can coordinate their motions to exploit their fluid environment—and each other—to achieve global advantages in their locomotory performance.

Microswimmers in vortices: dynamics and trapping
Soft Matter, 2022 We theoretically investigate the dynamics of model microswimmers in singular vortices, discover the existence of bounded orbits and use the model to successfully explain the previously observed depletion zone in bacterial suspensions.

Gait switching and targeted navigation of microswimmers via deep reinforcement learning
Communications Physics, 2022 Biomedical applications of artificial microswimmers rely on efficient navigation strategies within complex and unpredictable fluid environments. Here, the authors use artificial intelligence to model and design microswimmers that are capable of self ...

Collective motion in a sheet of microswimmers [PDF]
Communications Physics, 2023 Understanding the mechanisms that shape collective swimming of microorganisms is of great interest in biology, ecology and physics. Here the authors show that geometric constraints on the swimmers’ dynamics, such as near a solid surface, significantly ...

Journal of the Physical Society of Japan, 2021 We propose a model for a thermally driven microswimmer in which three spheres are connected by two springs with odd elasticity. We demonstrate that the presence of odd elasticity leads to the directional locomotion of the stochastic microswimmer.

Microswimmers in an axisymmetric vortex flow
New Journal of Physics, 2020 Microswimmers are encountered in a wide variety of biophysical settings. When interacting with flow fields, they show interesting dynamical features such as hydrodynamic trapping, clustering, and preferential orientation.

Minimum entropy production by microswimmers with internal dissipation [PDF]
Nature Communications, 2023 The energy dissipation and entropy production by self-propelled microswimmers differ profoundly from passive particles pulled by external forces.
