Boundary- and Screening-Induced Bubbly Phases in Autophoretic Active Matter
Kingshuk Panja, Günther Turk, Rajesh Singh
Spatial confinement and chemical screening fundamentally reshape the non-equilibrium phase behavior of autophoretic active particles. Here, we present a systematic study mapping th…

Autophoresis of a Janus particle near a planar wall: a lubrication limit
Tachin Ruangkriengsin, Günther Turk, Howard A. Stone
We study the self-diffusiophoresis of a spherical chemically active particle near a planar, impermeable wall, with a focus on the influence of particle orientation on propulsion. W…

Autophoretic skating along permeable surfaces
Günther Turk, Rajesh Singh, Howard A. Stone
The dynamics of self-propelled colloidal particles are strongly influenced by their environment through hydrodynamic and, in many cases, chemical interactions. We develop a theoret…
