Exact solution of the five frequency model of the vacancy-assisted impurity diffusion in the limit of vanishing vacancy concentration
V. I. Tokar
The van Hove autocorrelation function of the impurity is obtained which is exact to the first order in the vacancy concentration. It is found that in the case of strong vacancy-imp…

Non-equilibrium gelation transition in a kinetic lattice gas model
V. I. Tokar, H. Dreyssé
We consider a lattice gas model which in addition to the canonical nearest neighbor pair interatomic interaction accounts for a many-body interaction inside atomic trios. Interacti…
