Stochastic thermodynamics of active Brownian particles
, 2013 Examples of self propulsion in strongly fluctuating environment is abound in nature, e.g., molecular motors and pumps operating in living cells. Starting from Langevin equation of motion, we develop a fluctuating thermodynamic description of self ...

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 ...

Rational design and dynamics of self-propelled colloidal bead chains: from rotators to flagella
, 2017 The quest for designing new self-propelled colloids is fuelled by the demand for simple experimental models to study the collective behaviour of their more complex natural counterparts. Most synthetic self-propelled particles move by converting the input

Binding self-propelled topological defects in active turbulence
Physical Review Research, 2020 We report on the emergence of stable self-propelled bound defects in monolayers of active nematics, which form virtual full-integer topological defects in the form of vortices and asters.

Self-Propelled Particle Model for Cell-Sorting Phenomena [PDF]
Physical Review Letters, 2008 A self-propelled particle model is introduced to study cell sorting occurring in some living organisms. This allows us to evaluate the influence of intrinsic cell motility separately from differential adhesion with fluctuations, a mechanism previously shown to be sufficient to explain a variety of cell rearrangement processes. We find that the tendency

Universal properties of repulsive self-propelled particles and attractive driven particles
Physical Review ResearchMotility-induced phase separation (MIPS) is a nonequilibrium phase separation that has a different origin from equilibrium phase separation induced by attractive interactions.

Collective behavior of interacting self-propelled particles
, 2006 We discuss biologically inspired, inherently non-equilibrium self-propelled particle models, in which the particles interact with their neighbours by choosing at each time step the local average direction of motion.

New Journal of Physics, 2017 We study the appearance and properties of cluster crystals (solids in which the unit cell is occupied by a cluster of particles) in a two-dimensional system of self-propelled active Brownian particles with repulsive interactions.

Transport of active ellipsoidal particles in ratchet potentials
, 2014 Rectified transport of active ellipsoidal particles is numerically investigated in a two-dimensional asymmetric potential. The out-of-equilibrium condition for the active particle is an intrinsic property, which can break thermodynamical equilibrium and ...

Crystallization in a dense suspension of self-propelled particles
, 2011 Using Brownian dynamics computer simulations we show that a two-dimensional suspension of self-propelled ("active") colloidal particles crystallizes at sufficiently high densities.
