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.

Brownian Motion and Diffusion

1989
Let us pause in this chapter for a little intermezzo with a discussion of the generalized diffusion equation (36.18). We express the momentum density g in terms of the particle current density j as g(x,t) = mj(x,t).

Brownian diffusion in a nonuniform gas

Journal of Statistical Physics, 1971
An analysis is made of the effects on the diffusion of Brownian particles whose Knudsen number is large compared to unity, of nonuniformities in the host gas. As examples, in one type of nonuniformity of the host gas, the Chapman-Enskog velocity distribution function for the gas molecules is used; in the other, the host gas is a free-molecule Couette ...

Brownian Diffusion in a Dilute Dispersion of Droplets

Journal of Colloid and Interface Science, 1999
An analytical study of Brownian motion in a dispersion of fluid drops is considered. The droplets, which are spherical and may differ in radius, are assumed to be close enough to interact hydrodynamically. Based on Einstein's description of Brownian motion that invokes an equilibrium and in which droplets are affected by a thermodynamic force, the ...

DIFFUSION PROCESSES WITH RESPECT TO FREE BROWNIAN MOTION

Infinite Dimensional Analysis, Quantum Probability and Related Topics, 2000
We prove the existence, uniqueness and Markov property for SDE of diffusion type in the context of the stochastic analysis on the free Fock space introduced in Ref. 1.

Brownian motion and diffusion of spins

Physics Letters A, 1968
Abstract An analogy has been drawn between the description of particle diffusion in gases or liquids and spin diffusion in ferromagnets.
