Abstract
A pairwise particle-exchange model on a linear lattice is solved exactly by a new rate-equation method. Lattice sites are occupied by particles A and B which can exchange irreversibly provided the local energy is reduced. Thus, the model corresponds to a zero-temperature Kawasaki-type phase separation process. As a result of local order parameter conservation, the dynamics reaches a frozen state at large times, the structure of which depends on the initial conditions.Keywords
