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.

Effective Viscosity of Microswimmer Suspensions [PDF]
Physical Review Letters, 2010 The measurement of a quantitative and macroscopic parameter to estimate the global motility of a large population of swimming biological cells is a challenge Experiments on the rheology of active suspensions have been performed. Effective viscosity of sheared suspensions of live unicellular motile micro-algae (\textit{Chlamydomonas Reinhardtii}) is far

Advanced Intelligent Systems, 2020 In nature, most microorganisms have motility, which is essential for their survival or reproduction. To move, some microorganisms have evolved soft spiral‐shaped flagella, which rotate through specialized motors.

Collective motion in microswimmer suspensions [PDF]
, 2023 The main distinction of active matter from its passive counterpart is the ability to extract energy from the environment (consume food) and convert it into directed motion.

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.

Propulsion and energetics of a minimal magnetic microswimmer [PDF]
, 2020 In this manuscript we describe the realization of a minimal hybrid microswimmer, composed of a ferromagnetic nanorod and a paramagnetic microsphere. The unbounded pair is propelled in water upon application of a swinging magnetic field that induces a ...

Hydrodynamics of an odd active surfer in a chiral fluid
New Journal of Physics, 2023 We theoretically and computationally study the low-Reynolds-number hydrodynamics of a linear active microswimmer surfing on a compressible thin fluid layer characterized by an odd viscosity.
