Abstract

Motivated by recent experiments, we study a system of self-propelled colloids that experience short-range attractive interactions and are confined to a surface. Using simulations we find that the phase behavior for such a system is reentrant as a function of activity: phase-separated states exist in both the low- and high-activity regimes, with a homogeneous active fluid in between. To understand the physical origins of reentrance, we develop a kinetic model for the system's steady-state dynamics whose solution captures the main features of the phase behavior. We also describe the varied kinetics of phase separation, which range from the familiar nucleation and growth of clusters to the complex coarsening of active particle gels.

  28. Neglecting hydrodynamic coupling can be justified by restricting the domain of applicability to motile cells on a surface [7], by noting that hydrodynamic coupling is screened and decays rapidly in space for particles close to a hard wall [29,30], or by observing as in two recent studies of active colloids [8,16] that the collective phenomena observed in experiments can be well reproduced in simulations without including hydrodynamic interactions.
