Colloidal Entrainment

figure2Particle entrainment by Raphaël, just accepted on Nat Com!

What happens to passive microparticles within a suspension of microorganisms? If the particles are small, they can be entrained over large distances by the micro swimmers. These interactions are rare, but their magnitude is large and -as it turns out- they end up dominating particle dynamics, which now resembles a jump-diffusion process. This is presented and discussed in details in a new work led by Raphaël, just accepted on Nature Communications. A preprint of the article (well.. a previous version) is currently available on the Arxiv.

Update. The article is now available here.
