Abstract
We study diffusion of optical excitation as a function of the ratio of the temperature to the inhomogeneous linewidth Δ. When T≪Δ the diffusion constant associated with one-phonon-assisted dipolar transfer over a Gaussian line is suppressed by the factor exp[−aΔ2/T2]. The effect is attributed to a decrease in the effective density of ions participating in the transfer.Keywords
