Active Brownian particles (ABPs), obeying a nonlinear Langevin equation with speed-dependent drift and noise amplitude, are well-known models used to describe self-propelled motion in biology. In… (More)
We study the problem of a Brownian particle diffusing in finite dimensions in a potential given by ψ = 2/2 where is Gaussian random field. Exact results for the diffusion constant in the high… (More)
Cette these presente l''etude de la dynamique de modeles, dans le cadre de la transition vitreuse dont une comprehension complete echappe encore a la physique moderne. Nous avons donc, a l'aide de… (More)
We study the problem of the computation of the effective diffusion constant of a Brownian particle diffusing in a random potential which is given by a function V() of a Gaussian field . A… (More)
We study the Langevin dynamics of a dipole diffusing in a random electrical field E derived from a quenched Gaussian potential. We show that in a suitable adiabatic limit (where the dynamics of the… (More)
This paper describes how the monitoring of air quality on the urban agglomerations is a priority today and, within this framework, the benzene, toluene and xylene (BTX) concentrations are regularly… (More)
