Trapping Reactions with Randomly Moving Traps: Exact Asymptotic Results for Compact Exploration
G. Oshanin, O. Benichou, M. Coppey +1
In a recent Letter Bray and Blythe have shown that the survival probability P(t) of an A particle diffusing with a diffusion coefficient D_A in a 1D system with diffusive traps B i…
The Atomic Slide Puzzle: Self-Diffusion of an Impure Atom
0. Benichou, G. Oshanin
In a series of recent papers van Gastel et al have presented first experimental evidence that impure, Indium atoms, embedded into the first layer of a Cu(001) surface, are not loca…
Ultra-Slow Vacancy-Mediated Tracer Diffusion in Two Dimensions: The Einstein Relation Verified
O. Benichou, G. Oshanin
We study the dynamics of a charged tracer particle (TP) on a two-dimensional lattice all sites of which except one (a vacancy) are filled with identical neutral, hard-core particle…
Stokes formula and density perturbances for driven tracer diffusion in an adsorbed monolayer
O. Benichou, A. M. Cazabat, J. De Coninck +2
We study the intrinsic friction of monolayers adsorbed on solid surfaces from a gas phase or vapor. Within the framework of the Langmuir model of delocalized adsorption, we calcula…
Directed random walk in adsorbed monolayer
O. Benichou, A. M. Cazabat, M. Moreau +1
We study the dynamics of a tracer particle, which performs a totally directed random walk in an adsorbed monolayer composed of mobile hard-core particles undergoing continuous exch…
Biased diffusion in a one-dimensional adsorbed monolayer
O. Benichou, A. M. Cazabat, A. Lemarchand +2
We study dynamics of a probe particle, which performs biased diffusive motion in a one-dimensional adsorbed monolayer of mobile hard-core particles undergoing continuous exchanges…
