Bath-modes quantitatively capture the nonlinear microrheology of micellar solutions

Pierre Champagnac, Clemens Bechinger, Juliana Caspers +3

Active microrheology experiments, in which a probe is driven through a complex fluid, often exhibit nonlinear responses that cannot be captured by generalized Langevin equations. M…

Time-dependent dynamics in the confined lattice Lorentz gas

A. Squarcini, A. Tinti, P. Illien +2

We study a lattice model describing the non-equilibrium dynamics emerging from the pulling of a tracer particle through a disordered medium occupied by randomly placed obstacles. T…

Dimensional crossover via confinement in the lattice Lorentz gas

A. Squarcini, A. Tinti, P. Illien +2

We consider a lattice model in which a tracer particle moves in the presence of randomly distributed immobile obstacles. The crowding effect due to the obstacles interplays with th…

Universal scale-free decay of tracer-bath correlations in -dimensional interacting particle systems

Davide Venturelli, Pierre Illien, Aurélien Grabsch +1

Quantifying the correlations between the position of a tagged tracer and the density of surrounding bath particles is crucial for understanding tracer diffusion in interacting part…

Dynamics of soft interacting particles on a comb

Davide Venturelli, Pierre Illien, Aurélien Grabsch +1

We study the dynamics of overdamped Brownian particles interacting through soft pairwise potentials on a comb-like structure. Within the linearized Dean-Kawasaki framework, we char…
