Non-Boltzmann classical correction to the velocity auto-correlation function for isotropic scattering in two dimensions
Alexander Dmitriev, Michel Dyakonov, Remi Jullien
The classical correction to the velocity auto-correlation function of non-interacting particles due to memory effects, which are beyond the Boltzmann equation, is calculated both a…
Sodium diffusion through amorphous silica surfaces: A molecular dynamics study
Michael Rarivomanantsoa, Philippe Jund, Remi Jullien
We have studied the diffusion inside the silica network of sodium atoms initially located outside the surfaces of an amorphous silica film. We have focused our attention on structu…
New universality class for the three-dimensional XY model with correlated impurities: Application to He in aerogels
Carlos Vásquez-Romero, R. Paredes-Villegas, A. Hasmy +1
Encouraged by experiments on He in aerogels, we confine planar spins in the pores of simulated aerogels (diffusion limited cluster-cluster aggregation) in order to study the ef…
Anomalous Low-Field Classical Magnetoresistance in Two Dimensions
Alexander Dmitriev, Michel Dyakonov, Remi Jullien
The magnetoresistance of classical two-dimensional electrons scattered by randomly distributed impurities is investigated by numerical simulation. At low magnetic fields, we find f…
Matrix controlled channel diffusion of sodium in amorphous silica
E. Sunyer, P. Jund, R. Jullien
To find the origin of the diffusion channels observed in sodium-silicate glasses, we have performed classical molecular dynamics simulations of NaO--4SiO during which the m…
