Phase separation of self-propelled ballistic particles
Physical Review E, 2018 Self-propelled particles phase separate into coexisting dense and dilute regions above a critical density. The statistical nature of their stochastic motion lends itself to various theories that predict the onset of phase separation. However, these theories are ill equipped to describe such behavior when noise become negligible.

Advanced Materials, EarlyView.This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Rheological properties of a dilute suspension of self-propelled particles
, 2015 With a detailed microscopic model for a self-propelled swimmer, we derive the rheological properties of a dilute suspension of such particles at small Peclet number. It is shown that, in addition to Einstein's like contribution to the effective viscosity,

Experimental observation of flow fields around active Janus spheres
Nature Communications, 2019 In order to predict the behaviours of self-propelled particles it is important to understand the fluid disturbances they generate. Here the authors measure the flow-fields around active particles and show that they are in agreement with theoretical ...

Guided accumulation of active particles by topological design of a second-order skin effect
Nature Communications, 2021 Sustainable strategies for shepherding active particles are at the heart of many prospective applications. Here, Palacios et al. use the emerging topological properties of a microfluidic maze array to passively guide self-propelled colloids from the ...

Collective Motion of Self-Propelled Particles with Memory
Physical Review Letters, 2015 We show that memory, in the form of underdamped angular dynamics, is a crucial ingredient for the collective properties of self-propelled particles. Using Vicsek-style models with an Ornstein-Uhlenbeck process acting on angular velocity, we uncover a rich variety of collective phases not observed in usual overdamped systems, including vortex lattices ...

Kramers escape of a self-propelled particle [PDF]
The European Physical Journal B, 2016 We investigate the escape rate of an overdamped, self-propelled spherical Brownian particle on a surface from a metastable potential well. Within a modeling in terms of a 1D constant speed of the particle's active dynamics we consider the associated rate using both numerical and analytical approaches. Regarding the properties of the stationary state in

Dynamics of Self-Propelled Particles: Diffusion, Motility-Sorting, and Rectification [PDF]
, 2015 Self-propelled particles, or active particles, continuously convert stored energy into kinetic energy, and are therefore intrinsically out of thermodynamic equilibrium.
