Using a recently developed microscopic theory of diffusion for a particle coupled to an inhomogeneous medium, it has been shown that in the case of a structural phase transition with a diverging central peak, a diffusion anomaly occurs. We review results of model calculations demonstrating this anomaly on the W(100) surface, as well as discuss other physical systems where analogous phenomena may be observed.
