The dynamic properties of a classical tracer particle in a random, disordered medium are investigated close to the localization transition. For Lorentz models obeying Newtonian and diffusive motion at the microscale, we have performed large-scale computer simulations, demonstrating that universality holds at long times in the immediate vicinity of the transition. The scaling function describing the crossover from anomalous transport to diffusive motion is found to vary extremely slowly and… 

The localization transition of the two-dimensional Lorentz model

Abstract. We investigate the dynamics of a single tracer particle performing Brownian motion in a two-dimensional course of randomly distributed hard obstacles. At a certain critical obstacle

Confined diffusion in a random Lorentz gas environment.

The diffusive behavior of biased Brownian particles in a two dimensional confined geometry filled with the freezing obstacles is studied and a relation between η and f is found which provides an estimate of the minimum η up to a critical scaling parameter f_{c} beyond which the Fick-Jacobs description is invalid.

Crowding of Interacting Fluid Particles in Porous Media through Molecular Dynamics: Breakdown of Universality for Soft Interactions.

The soft interactions are responsible for the breakdown of the universality of the dynamics of the Lorentz model scenario, as the system exhibits a transition from a diffusive to a localized state, but the transition is strongly rounded.

Anomalous transport of a tracer on percolating clusters

The dynamics of a single tracer exploring a course of fixed obstacles in the vicinity of the percolation transition for particles confined to the infinite cluster shows anomalous transport, which extends to infinite times precisely at the critical obstacle density.

Brownian motion of a self-propelled particle

Comparing the dynamics of real and artificial microswimmers, like bacteria or catalytically driven Janus particles, to the analytical expressions reveals whether their motion is Brownian or not.

Brownian motion of a self-propelled particle.

Overdamped Brownian motion of a self-propelled particle is studied by solving the Langevin equation analytically. On top of translational and rotational diffusion, in the context of the presented

Dynamic arrest in model porous media—intermediate scattering functions

Heterogeneous media constitute random disordered environments where transport is drastically hindered. Employing extensive molecular dynamics simulations, we investigate the spatio-temporal dynamics

Complex dynamics induced by strong confinement – From tracer diffusion in strongly heterogeneous media to glassy relaxation of dense fluids in narrow slits

Abstract We provide an overview of recent advances of the complex dynamics of particles in strong confinements. The first paradigm is the Lorentz model where tracers explore a quenched disordered



Crossover in the slow decay of dynamic correlations in the lorentz model.

The long-time behavior of transport coefficients in a model for spatially heterogeneous media in two and three dimensions is investigated by molecular dynamics simulations and the logarithmic divergence of the Burnett coefficient is corroborated in the dilute limit.

Transport properties of stochastic Lorentz models

Diffusion processes are considered for one-dimensional stochastic Lorentz models, consisting of randomly distributed fixed scatterers and one moving light particle. In waiting time Lorentz models the

Event-driven Brownian dynamics for hard spheres.

The authors discuss a general method for the overdamped Brownian dynamics of hard spheres, recently developed by one of the authors, and test the accuracy of the algorithm and its convergence for a number of analytically tractable test cases.

Simulation of self-diffusion of point-like and finite-size tracers in stochastically reconstructed Vycor porous glasses

Aim of the present study is to simulate self-diffusion in three-dimensional images of reconstructed Vycor porous glass, which have the same statistical content as the actual material in terms of

Properties of the density relaxation function in classical diffusion models with percolation transition

The relation between the density relaxation function Phi and the pair connectedness is shown. Static and dynamical scaling for Phi and quantities related to it are derived from percolation scaling

Diffusion of finite‐sized Brownian particles in porous media

The effective diffusion coefficient De for porous media composed of identical obstacles of radius R in which the diffusing particles have finite radius βR (β≥0) is determined by an efficient Brownian

Static and dynamic heterogeneities in a model for irreversible gelation.

In the sol phase close to the percolation threshold, it is found that this dynamic susceptibility increases with the time until it reaches a plateau, and an alternative way of measuring critical exponents in a system undergoing chemical gelation is suggested.

Localization transition of the three-dimensional lorentz model and continuum percolation.

A coherent and quantitative explanation of the dynamics in terms of continuum percolation theory is given and an excellent matching of the critical density and exponents is obtained.
