Microswimmers create bicontinuous emulsions in binary fluids
Harinadha Gidituri, Sotiris Samatas, Juho S. Lintuvuori
We consider a generic case of neutrally wetting microswimmers in symmetric mixtures of two phase separating fluids, using hydrodynamic simulations. The swimmers spontaneously emuls…
Emergent Synchronization and Defect Dynamics in Confined Chiral Active Suspensions
Zaiyi Shen, Leilei Wang, Shishuang Zhang +4
Hydrodynamic interactions can generate rich emergent structures in active matter systems. Using large-scale hydrodynamic simulations, we demonstrate that hydrodynamic coupling alon…
Interface crossing behavior of prolate microswimmers: thermo and hydrodynamics
Rishish Mishra, Harish Pothukuchi, Harinadha Gidituri +1
Motivated by recent experiments of motile bacteria crossing liquid-liquid interfaces of isotropic- nematic coexistence (Cheon et al., Soft Matter 20: 7313-7320, 2024), we study the…
Inertia-driven propulsion of asymmetric spinner-dimers at moderate Reynolds numbers
Zaiyi Shen, Dongfang Fu, Juho Lintuvuori
We investigate the translational motion of rotating colloidal systems at moderate Reynolds numbers (Re), focusing on particle dimers in snowman-like configurations under three scen…
Quantitative measurements of non-equilibrium interactions of catalytic microswimmers with dual colloidal tracers
Celso Carrasco, Quentin Martinet, Zaiyi Shen +3
Catalytic microswimmers convert the chemical energy of a fuel into motion, sustaining spatial chemical gradients and fluid flows that drive their propulsion. This leads to unconven…
Active microrheology of fluids with orientational order
J. S. Lintuvuori, A. Würger
We study the dynamics of a driven spherical colloidal particle moving in a fluid with a broken rotational symmetry. Using a nematic liquid crystal as a model, we demonstrate that w…
