The crossover from single-file diffusion, where the mean-square displacement scales as (x2) to approximately t(1/2), to normal Fickian diffusion, where (x2) to approximately t, is studied as a function of channel width for colloidal particles. By comparing Brownian dynamics to a hybrid molecular dynamics and mesoscopic simulation technique, we can study the effect of hydrodynamic interactions on the single file mobility and on the crossover to Fickian diffusion for wider channel widths.

Diffusion in quasi-one-dimensional channels: A small system n, p, T, transition state theory for hopping times.
TLDR
This paper develops a transition state theory approach to the calculation of the hopping time, using the small system isobaric-isothermal ensemble to rigorously account for the volume fluctuations associated with the size of the cage, and describes a Monte Carlo simulation scheme that can be used to calculate the free energy barrier for particle hopping.
Ordering and single-file diffusion in colloidal systems.
TLDR
It is demonstrated that one-dimensional systems, with particles interacting repulsively, show common structural and dynamical behaviors at the boundary in which the degree of ordering changes dramatically; the main peak of the static structure factor becomes highly narrow with a height of S(c)≈7, whereas the reduced mobility factor F, which is associated with the single-file diffusion at long-times or long wavelengths, reaches values F(∗)≆0.1.

A comprehensive review of the recent advances in the theory of SF dynamics with the purpose of spurring further experimental work is provided.
Non-monotonic crossover from single-file to regular diffusion in micro-channels
TLDR
A system in which the nature of the diffusion process varies with changes in the external conditions is presented, consisting of micron sized particles which are confined to narrow channels and interact via induced magnetic dipoles.
A transition state theory for calculating hopping times and diffusion in highly confined fluids.
TLDR
This work suggests that the combination of hopping times and transition state theory offers a useful and general framework to describe the dynamics of highly confined, single file fluids.
Microscopic diffusion coefficients of dumbbell- and spherocylinder-shaped colloids and their application in simulations of crowded monolayers.
TLDR
The determined empirical formulas for the microscopic diffusion coefficients add to the knowledge of the diffusion of anisotropic particles, and they can be used in countless future studies.
Structural transitions and long-time self-diffusion of interacting colloids confined by a parabolic potential.
TLDR
The Brownian dynamics simulations find that by varying the magnitude of the trap stiffness, it is possible to control the dimension of the system and explore both the structural transitions and the long-time self-diffusion coefficient as a function of the degree of confinement.

TLDR
A one disk model which partially mimics the two disks problem is studied in the infinitely anisotropic diffusion limits and exponents from numerical solutions which are consistent with each other and the proposed exact value are obtained.

TLDR
Even with simple hard-core repulsion between the interfaces and the particles, diffusion is found to depend strongly on the details of the dynamical rules of particles close to the interfaces.

From random walk to single-file diffusion.
TLDR
The dependence of the 1D mobility in the SFD on the concentration of the colloids agrees quantitatively with that derived for a hard rod model, which confirms for the first time the validity of the hard rod SFD theory.
Hopping time of a hard disk fluid in a narrow channel.
TLDR
This work uses Monte Carlo and molecular dynamics methods to study the self-diffusion of hard disk fluids, confined within a narrow channel, and indicates that the scaling law exponent does not appear to be dependent on the differences between the two dynamics.
Single-file diffusion of atomic and colloidal systems: asymptotic laws.
TLDR
The asymptotic behavior of the mean-squared displacement, W(t), is shown to be independent of the nature of interactions for homogeneous systems in the fluid state and the long-time behavior of self-diffusion is determined by short-time and large-scale collective density fluctuations.

The one disk model is similar to a disk diffusing in a two-dimensional container, shaped as a simplified configuration space of two passing disks in a flat channel of Kalinay, and predicts exponents of 1 and 12.

A theoretical formalism is suggested that will be useful for the calculation of tau(hop) for a variety of systems and is tested using a simple model consisting of two hard disks confined to a rectangular box with hard walls.

This work reports on recent advances in the theoretical and numerical investigation of stochastic transport occurring either in microsized geometries of varying cross sections or in narrow channels wherein the diffusing particles are hindered from passing each other (single-file diffusion).
