Perturbation theory for the effective diffusion constant in a medium of random scatterer
D. S. Dean, I. T. Drummond, R. R. Horgan +1
We develop perturbation theory and physically motivated resummations of the perturbation theory for the problem of a tracer particle diffusing in a random media. The random media c…

Effective diffusion constant in a two dimensional medium of charged point scatterers
D. S. Dean, I. T. Drummond, R. R. Horgan
We obtain exact results for the effective diffusion constant of a two dimensional Langevin tracer particle in the force field generated by charged point scatterers with quenched po…
