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…

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…

Fluctuating hydrodynamics of an autophoretic particle near a permeable interface
Günther Turk, Ronojoy Adhikari, Rajesh Singh
We study the autophoretic motion of a spherical active particle interacting chemically and hydrodynamically with its fluctuating environment in the limit of rapid diffusion and slo…
