Abstract
We report on a molecular-dynamics study of a two-dimensional model system which is expected to exhibit antiferrodistortive structural phase transitions. The estimated values for the critical exponents and are close to those of the two-dimensional Ising model. The origin of a central peak in the dynamic form factor is attributed to the formation and the dynamics of clusters.
