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.

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 motors in nonlinear diffusive media

Physical Review E, 2007
We investigate the performance of Brownian motors in environments governed by the "porous medium" equation partial differential(t)rho = D partial differential(x) (rho(nu-1) partial differential(x)rho), where rho is the density and D and nu positive constants.

Bounded diffusing diffusivities: Brownian yet non-Gaussian diffusion

Physica Scripta
Abstract Brownian yet non-Gaussian diffusion has been recently reported in a huge number of biological and soft matter systems. Meanwhile, an archetypal theoretical model called ‘diffusing diffusivities’ is proposed to interpret it. Based on this spirit of diffusing diffusivities, we extend the original diffusing diffusivities (with the ...
