摘要:
We discuss the stochastic motion of atoms in a supercooled fluid near the glass transition point on the basis of the trapping diffusion model. We obtain the dynamical singularities in the mean square displacement, diffusion constant, incoherent scattering function and non‐Gaussian parameter. It is shown that the stochastic jump motion produces &agr;‐type relaxation.
