The term single file (SF) dynamics refers to the motion of an assembly of particles through a
channel with cross-sections comparable to the particles' diameter. Single file diffusion (SFD) …

We study the dynamics of a tagged particle in an environment of point Brownian particles
with hard-core interactions in an infinite one-dimensional channel (a single-file model). In …

In colloidal systems, Brownian motion emerges from the massive separation of time and
length scales associated with characteristic dynamics of the solute and solvent constituents …

This thesis both broadens and deepens our understanding of the Brownian world. It
addresses new problems in diffusion theory that have recently attracted considerable …

We discuss various models of ion transport through cell membrane channels. Recent
experimental data shows that sizes of some ion channels are compared to those of ions and …

We study with numerical simulations the transverse fluctuations in quasi-one-dimensional
systems of particles in a thermal bath, near the zigzag transition. We show that close to the …

We report on the dynamical properties of interacting colloids confined to one dimension and
subjected to external periodic energy landscapes. We particularly focus on the influence of …

We investigate the long-time behavior of the survival probability of a tagged particle in a
single-file diffusion in a finite interval. The boundary conditions are of two types:(1) one …

We study the zigzag transition in a system of particles with screened electrostatic interaction,
submitted to a thermal noise. At finite temperature, this configurational phase transition is an …

Dynamics of a one-dimensional system of Brownian particles with short-range repulsive
interaction (diameter σ) is studied with a liquid-theoretical approach. The mean square …
