Description
Squirmers provide a simple and effective model for active particles. We consider the particular case of shakers (non-self-propelling squirmers) confined to a fluid-fluid interface, so that an ultraconfined 2D colloid immersed in a 3D fluid is obtained. This dimensionally hybrid (2D/3D) configuration alters the hydrodynamic interactions significantly due to the symmetry breaking of the orientational isotropy of shakers and the effective 2D compressibility of the projected in-plane 3D flow. We study the collective dynamics of such system analytically and numerically, and we highlight some features following specifically from the modified hydrodynamic interactions.
