Formation and collision of traveling bands in interacting deformable self-propelled particles.
We study the collective dynamics of interacting deformable self-propelled particles whose migration velocity increases with increasing local density. In two-dimensional numerical simulations of this system, the local density dependence on migration velocity leads to traveling bands similar to those previously reported for Vicsek-type models. We show that a pair of straight bands moving in oppos...
متن کاملSelf - propelled particles driven by light
In dieser Arbeit untersuche ich die wesentlichen Eigen-schaften biologischer und künstlicher aktiver Systeme undstelle eine neue Technik zur Herstellung von selbstgetriebe-nen mikroskopischen Kolloiden vor. Um den Antrieb zuerhalten nutzen wir phoretische Kräfte, welche ins Spielkommen, wenn ein Janus-Teilchen seine Umgebung asym-metrisch verändert. Erheblicher experimen...
متن کاملThe collective dynamics of self - propelled particles
We have proposed a method for the dynamic simulation of a collection of self-propelled particles in a viscous Newtonian fluid. We restrict attention to particles whose size and velocity are small enough that the fluid motion is in the creeping flow regime. We have proposed a simple model for a self-propelled particle, and extended the Stokesian Dynamics method to conduct dynamic simulations of ...
متن کاملSpontaneously ordered motion of self-propelled particles
We study a biologically inspired, inherently non-equilibrium model consisting of self-propelled particles. In the model, particles move on a plane with a velocity of constant magnitude; they locally interact with their neighbours by choosing at each timestep a velocity direction equal to the average direction of their neighbours. Thus, in the limit of vanishing velocities the model becomes anal...
متن کاملGravitaxis of asymmetric self-propelled colloidal particles.
Many motile microorganisms adjust their swimming motion relative to the gravitational field and thus counteract sedimentation to the ground. This gravitactic behaviour is often the result of an inhomogeneous mass distribution, which aligns the microorganism similar to a buoy. However, it has been suggested that gravitaxis can also result from a geometric fore-rear asymmetry, typical for many se...
