Abstract
The dynamic properties of dipolar and quadrupolar glasses are discussed on the basis of a recently developed symmetry-adapted random bond-random field model. Starting from a set of Langevin-type stochastic equations of motion, dynamic equations for the self-consistent propagator are derived in the mean-field limit. Using a scaling form for the correlation function, the temperature dependence of the effective scaling exponent νeff observed in dielectric relaxation experiments is calculated.
