Schematic models for active nonlinear microrheology

We analyze the nonlinear active microrheology of dense colloidal suspensions using a schematic model of mode-coupling theory. The model describes the strongly nonlinear behavior of the microscopic…

Active microrheology in a colloidal glass.

This nonequilibrium and anisotropic problem is investigated using a new implementation of the mode-coupling approximation with multiple relaxation channels and Langevin dynamics simulations, finding a force threshold below which the probe remains localized, while above it the probe acquires a finite velocity.

Nonequilibrium depletion interactions in active microrheology.

The nonequilibrium forces mediated by the depletants on the two colloidal particles within a dynamical superposition approximation (DSA) scheme are calculated and the colloidal microstructure around the driven probe is obtained.

Active nonlinear microrheology in a glass-forming Yukawa fluid.

A molecular dynamics computer simulation of a glass-forming Yukawa mixture is used to study the anisotropic dynamics of a single particle pulled by a constant force. Beyond linear response, a scaling…

Time-dependent active microrheology in dilute colloidal suspensions

Abstract In a microrheological set-up a single probe particle immersed in a complex fluid is exposed to a strong external force driving the system out of equilibrium. Here, we elaborate analytically…

Force-induced diffusion in microrheology

A schematic model of mode-coupling theory introduced recently is extended to describe the transient dynamics of the probe particle, and used to analyze recent molecular-dynamics simulation data.

Driven motion of colloids in active microrheology

In active microrheology, a strong external force is applied to a colloidal probe immersed in a complex fluid, so that among other quantities the nonlinear force-velocity relation can be measured. It…

Nonlinear response and crowding effects in microrheology.

The mobility of tagged particles in a microrheological setup has been investigated via molecular dynamics simulations of a three-dimensional Lennard-Jones binary mixture and significant crowding effects are observed, thereby creating stringlike structures.
