When Brownian diffusion is not Gaussian

Nature Materials, 2012
It is commonly presumed that the random displacements that particles undergo as a result of the thermal jiggling of the environment follow a normal, or Gaussian, distribution. However, non-Gaussian diffusion in soft materials is more prevalent than expected.

Brownian Diffusion Close to a Polymer Brush

Langmuir, 2007
In an effort to control particle diffusion near surfaces, we have studied the dynamics of colloidal hard spheres and soft compliant star copolymers on surfaces coated with polymer brushes using evanescent wave dynamic light scattering. The same experiments provide information on the brush structure and confined particle motion.

Diffusion and Brownian motion in Lagrangian coordinates

The Journal of Chemical Physics, 2007
In this paper we consider the convection-diffusion problem of a passive scalar in Lagrangian coordinates, i.e., in a coordinate system fixed on fluid particles. Both the convection-diffusion partial differential equation and the Langevin equation are expressed in Lagrangian coordinates and are shown to be equivalent for uniform, isotropic diffusion ...

Brownian Motion and Diffusions

2011
Multi-skewed Brownian motion Bα = {Bαt: t ≥ 0} with skewness sequence α = {αk: k ∈ Z} and interface set S = {xk: k ∈ Z} is the solution to Xt = X0 + Bt + ∫R LX(t, x)dμ(x) with μ = ∑k∈Z(2αk - 1)δxk We assume that αk ∈ (0, 1)\{1/2} and that S has no accumulation points.

Diffusion of interacting Brownian particles: Jamming and anomalous diffusion

Physical Review E, 2006
The free self-diffusion of an assembly of interacting particles confined on a quasi-one-dimensional ring is investigated both numerically and analytically. The interparticle pairwise interaction can be either attractive or repulsive and the energy barrier opposing thermal hopping of two particles one past the other is finite.

Brownian diffusion of a partially wetted colloid

Nature Materials, 2015
The dynamics of colloidal particles at interfaces between two fluids plays a central role in microrheology, encapsulation, emulsification, biofilm formation, water remediation and the interface-driven assembly of materials. Common intuition corroborated by hydrodynamic theories suggests that such dynamics is governed by a viscous force lower than that ...
