Effect of reorientation statistics on torque response of self-propelled particles.
نویسندگان
چکیده
We consider the dynamics of self-propelled particles subject to external torques. Two models for the reorientation of self-propulsion are considered: run-and-tumble particles and active Brownian particles. Using the standard tools of nonequilibrium statistical mechanics we show that the run and tumble particles have a more robust response to torques. This macroscopic signature of the underlying reorientation statistics can be used to differentiate between the two types of self-propelled particles.

The force on a boundary in active matter
We present a general theory for determining the force (and torque) exerted on a boundary (or body) in active matter. The theory extends the description of passive Brownian colloids to self-propelled active particles and applies for all ratios of the thermal energy kBT to the swimmer’s activity ksTs = ζU 2 0 τR/6, where ζ is the Stokes drag coefficient, U0 is the swim speed and τR is the reorien...
متن کاملImage-based Magnetic Control of Self-propelling Catalytic Micro Motors
This paper describes our work to magnetically steer self-propelled devices which move by catalysis of hydrogen peroxide. We demonstrate manipulation of paramagnetic particles with a diameter of 100μm to a given setpoint by means of magnetic field gradients, as well as self-propelled movement of gold-platinum rods. We discuss how to reach magnetic torque control of catalytic micro motors.
متن کاملNumerical investigation of a fleet of self-propelled AUVs
This paper investigates the influence of the propeller on the drag of twin self-propelled AUVs, firstly, to examine the fleet performance for various propulsive conditions of leading and following AUV and, secondly, to study the parametric influence of transverse separations and longitudinal offsets on the fleet’s drag. A series of CFD RANS-SST simulations have been performed at the Reynolds Nu...
متن کاملSelf-propelled hard disks: implicit alignment and transition to collective motion
We formulate a model of self-propelled hard disks whose dynamics is governed by mutually coupled vectors for velocity and body orientation. Numerical integration at low densities reveals that the expected transition from isotropic to aligned collective motion is present. However, the transition at the Landau meanfield level is strongly first-order, while it is continuous in the Vicsek model. We...
متن کاملDiffusion of chiral Janus particles in a sinusoidal channel
We investigated the transport diffusivity of artificial microswimmers, a.k.a. Janus particles, in the absence of external biases. We considered the case of chiral Janus particles moving either in the bulk or in sinusoidal channels with reflecting walls. Their self-diffusion constants turned out to depend on both the strength and the chirality of the self-propulsion mechanism. More importantly, ...
