Propagating Density Spikes in Light-Powered Motility-Ratchets
Celia Lozano, Benno Liebchen, Borge ten Hagen +2
Combining experiments and computer simulations, we use a spatially periodic and flashing light-field to direct the motion of phototactic active colloids. Here, the colloids self-or…

Colloidal Brazil nut effect in microswimmer mixtures induced by motility contrast
Soudeh Jahanshahi, Celia Lozano, Borge ten Hagen +2
We numerically and experimentally study the segregation dynamics in a binary mixture of microswimmers which move on a two-dimensional substrate in a static periodic triangular-like…
